It doesn't matter what your story is, when you had your period, how many times you had sex, if he did or didnt, if you're on birth control, whether or not the condom broke, or anything. You always have a chance of being pregnant, and that's exactly what we're going to tell you. So before you post, test! You can test 4 days before your first missed period, so don't ask us your chances of being pregnant, just test!!

Common things that can mess up your cycle:
1) stress
2) starting birth control
3) stopping birth control
4) switching birth control methods
5) puberty and natural horomonal changes
6) not eating enough or dieting
7) taking horomones, steroids, or other prescription drugs
8 ) illness

the science bit.

*sperm can live for upto 5 days inside the female body.

*an egg is viable for upto 36 hours after ovulation.

*ovulation typically occurs 14 days before not after your period (regardless of cycle length).

*it is rare for the luteal (post ovulation) phase to change, a longer cycle usually means you ovulate later.

*it is impossible to know exactly when you ovulate, without being a dedicated long term charter. Therefore it is impossible to say exactly when you are fertile.

*pregnancy is a risk you take any time you have sex (even on b/c because that is only, at best, 98-99% effective).

*day one of the cycle is the first day of bleeding.

*therefore your window of highest fertility is from 5 days prior to ovulation until 2 days after.

Based on an average 28 day cycle - days 09 - 16
based on an average 30 day cycle - days 10 - 18
based on an average 35 day cycle - days 15 - 23
based on an average 40 day cycle - days 20 - 28

this does not mean that you can't get pregnant at any other time, because it is possible dependant on your own personal cycle and time of ovulation - these are just typical averages for the window when are are most likely to be most fertile.

ok! Here goes - questions on a postcard please.

scrotum - this sac hangs outside the body and holds the testicles and epididymis. The scrotum automatically tightens up to keep the testicles warm or hangs low to help cool them off.

testicles - the 2 testicles, or testes, produce and store millions of tiny sperm cells. The testicles are oval-shaped and grow to be about 2 inches (5 centimeters) in length and 1 inch (3 centimeters) in diameter. The testicles are also part of the endocrine system because they produce hormones, including testosterone.

epididymis - a set of coiled tubes (one for each testicle) that connects to the vas deferens.

seminal vesicle - are sac-like structures attached to the vas deferens to the side of the bladder

prostate gland - produces some of the parts of semen, surrounds the ejaculatory ducts at the base of the urethra, just below the bladder.

vas deferens - a muscular tube that passes upward alongside the testicles and transports the sperm-containing fluid called semen

bladder - where urine collects.

urethra - the channel that carries the semen to the outside of the body through the penis. The urethra is also part of the urinary system because it is also the channel through which urine passes as it leaves the bladder and exits the body.

penis - made up of 2 parts: the shaft and the glans. The shaft is the main part of the penis and the glans is the tip (sometimes called the head). At the end of the glans is a small slit or opening, which is where semen and urine exit the body through the urethra. The inside of the penis is made of a spongy tissue that can expand and contract.

sperm production - once a male has reached puberty, he will produce millions of sperm cells every day. Each sperm is extremely small: only 1/600 of an inch (0.05 millimeters) long. Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells, but during puberty, testosterone and other hormones cause these cells to transform into sperm cells. The cells divide and change until they have a head and short tail, like tadpoles. The head contains genetic material (genes). The sperm use their tails to push themselves into the epididymis, where they complete their development. It takes sperm about 4 to 6 weeks to travel through the epididymis.

The sperm then move to the vas deferens, or sperm duct. The seminal vesicles and prostate gland produce a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated. The penis, which usually hangs limp, becomes hard when a male is sexually excited. Tissues in the penis fill with blood and it becomes stiff and erect (an erection). The rigidity of the erect penis makes it easier to insert into the female's vagina during sexual intercourse. When the erect penis is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra. Semen is pushed out of the male's body through his urethra - this process is called ejaculation. Each time a guy ejaculates, it can contain 250 - 500 million sperm.

if u have sex i weeks before ur period and the guy pull out can u before pregnant

well wonderful information.

Did you go to medical school? I did. for medical assisting and from my medical books and what the profs. taught, you only have a window of 24 hours to actuallly become pregnant. Pregnancy in itself is a wonder and a miracle. Make sure when giving advice, you have women know that each and everyone of us is different. Numbers are based off studies and studies are based of a certain no. of people. Numbers and percentages, in reality, don't mean a thing. If you think your pregnant, take the test. And also, I was pregnant with twins and at 4 months, I took a home test, did everything right, it was a name brand, and it still came out negative. The only true way to tell is to have you hcg levels checked. If they are greater than 5, time to take even better care of yourself.

thanks for the info i just got one question cuz imsure.
what does blue veins in your breats mean.
bc some ppl told me its a sure sign of when your prego.

I think this is a great forum for young teens who don't know about sex and what causes pregnancy. Everything you've stated I agree. Yes, everyone is different. In my case my boyfriend and I did the PULL-OUT method for 3 & half years! Never got pregnant it wasn't till November that I decided I wanted a baby with him. Now I am not saying everyone should do this and you wont get pregnant. It just didn't get me pregnant, but still better safe than sorry.

Thanks for posting this, there's a lot of information I was curious about. To the woman who did the pull out method, you are absolutely right the pull out method does not work for everyone. My fiance and I did the pull out method for 4 months and I'm pregnant.

I had 5 negative pregnancy tests,including 2 carried out at the doctor's surgery, and it wasn't until they actually decided to do an ultrasound,there my little boy was, just a little blob at 7 wks!so tests can come up negative!
I am sure i read somewhere too though that the hcg (human chorionic gonadatrophin)hormone only appears about 4 wks and rises rapidly until about 12 wks then its progesterone that takes over??
pregnancy tests do only test for hcg??so maybe that is another reason why you tested negative while pregnant at 4 months??

oh also in early pregnancy a lot of ppl test negative because they dont use the first urine sample of the day, therefore the hcg hormone hasnt had a chance to build up for passing urine.
its all a bit confusing really,lol!

I never knew you could obvulate more than once a month, Damnit
that was my birthcontrol i feel stuuupid
and im 2 days late
does new exercise mess with it too
ill just go get a test, just dont feel like wasting 20 bucks agian,,,,maybe ill wait,
how late is too late, like a week then no matter what get a test or could i wait longer??? I have 2 babies at home
i feel like ignoring arghh
but great info

I like the information that you gave out Kia.

well..i had my period 19th feb..it ended 24th fed.. i had sex on the 7/8th march.. since then i had real sore boobs,frequent loo trips ect,didnt notice discharge as i dnt monitor it that well..

so i was due on my period 19/20th march,but nothing...yesterday i wiped myself after the loo and there was a lil blood, same thing happened today..although there not really sore anymore i have bigger nipples,and they seem a lil bigger.. i had 2ned tests tho, one 2days after i was late and one last week..

help??? could i be pregnant? if so whats the bleeding?? and neg tests???

yes you could be. the blood could be implantation bleeding and a lot of people take tests up to 3 months before they know they are pregnant. If the blood is lighter than normally when you have your period and only lasts a few days that could be a good sign. hope i could help =]

brit143.. the blood was very light pink, it was only one tissue wipesworth both times.. i have to go get my blood results on monday so fingers crossed but could a blood test come up neg and i still be pregnant?

i had unproected sex with my boyfriend on march 1st for the frst time and then had unproected sex on march 10th and on march 14.. and in all the 3 days he cum inside of me.. can u tell we trying to have a baby lol but then got my period on march 18 it just last for 4 days.

can i be prgnanat

i disagree with half the stuff you have mention on your first like top 22 or something
for one you cannot get pregnant on you period
breast feeding really has nothing to do with getting pregnant yeah you can but what was the point of putting the on the top22

At the time, they probably had a lot of questions concerning breastfeeding and pregnancy. Why does it matter where they are in the list?

And you can get pregnant while on your period. The chances are pretty small, but its possible. There's really no day during a cycle where the chance of pregnancy is 0% and you don't even know if the person writing or reading is really talking about their actual period.
