I am on birth control, and have been for 10+ years. This month I was late taking a pill in the 2nd week by about 10 hours. I took it within the same 24 hour period, but it was late. I had no symptoms because of that. Afterwards, my fiancee and I used spermicide as a back up during intercourse.

My period arrived on schedule, yesterday, but it was light. Today it has not picked up. It is light brownish in color, with some red. I also have none of my regular symptoms such as back ache and minor cramping in the uterus. I have felt a little nausea here and there for the last 3 days. No tender breast, no dizziness, nothing.

I found a term, implantation bleeding, and wondered if that is what this is? Can you even have that when you are on the pill and not ovulating? So, how do you determine if it is spotting, a light flow, or implantation bleeding? Is any bleeding while on the pill considered a period because you do not ovulate? Does any bleeding while on the pill basically say you are not pregnant, since that is your "withdrawl bleed" and any fertilized egg would be flushed out at that point?

I have a pee-test to take in the morning, because that is the only sure fire way to know. I guess it just seems so unlikely and I wanted to know what the rest of the world thought too.

Thank you!

Hi,
Welcome to ehealthforum.
There can be chances of pregnancy due to contraceptive failure. The spotting, absence of usual pre-menstrual symptoms, lighter bleeding, nausea etc could also suggest pregnancy. The spotting could also suggest probable implantation bleed. Wait and watch for your periods and look out for development of any new symptoms suggestive of pregnancy. If you do not get periods within 10 days of expected period dates, or if you get abnormal periods, or if you develop any new symptoms, or if you suspect chances of pregnancy, you should consider visiting your doctor/gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet.
Take care.

Hi there! Thank you for your reply!

So, it is possible to have implantation bleeding while on birth control and it happened the day I was supposed to start my period?

No new symptoms, but the nausea subsided for a few days, then came back today. I took another HPT this past Friday, which would have been 11 days after the first day of spotting, and day 40 of my cycle. It was negative.

I am wondering if the stomach pains are a symptom of anxiety and possible ulcer? And is 11 days past missed period enough time to detect a pregnancy? Based on the times we have had sex, the most I could be is 4 weeks.

thank you!

I just wanted to post on here and follow up now that I have seen my doctor and know I am healthy and not pregnant. Also, because especially on this site the doctor responses (although helpful) do not give much detail, and do not offer many options besides pregnncy.

It is very common for women on a birth control pill, especially those who have been on it long term to have lighter to no periods. This happens because you are not having a true period you are having a withdrawl bleed. And you are not ovulating. So over time, the lining of hte uterus does not build up enough to shed anything of signifigance. I used to skip my inactive pills and only have a period every 3 months. Once I started having a period monthly, they became so light they were almost non-existant. It is okay to not have a period if you are on the pill, if you are using it correctly.

It is totally possible that one month you have average to heavy bleeding and the next month only spotting. And apparently this is even more common with certain pills like Yaz and Low Estrogen pills. If you do have missed to light periods for 2 months, take a test just to be sure.

Many early pregnancy symptoms are those also of PMS. So try to not read into your body too much (if you are on the pill). I was a basket case the last month or so, thinking that I might be pregnant. I gave myself acid reflux!! Which of course, heart burn is a sign of pregnancy....so you can see how my stress was creating even more stress!

The point is, even though you can search the internet for stories and opinions of women who have gotten pregnant while on the pill, chances are you are not IF you have been taking them correctly. If you take your pill EVERY DAY around the same time every day, you are more then likely not pregnant. If you are worried take a pregnancy test...or 2. Or if you are a total worry- wart about it like i was, go talk to your doctor in person. If you don't have a doctor go to a clinic.

Here are some things I have learned the last couple months to keep in mind if you are worried your birth control failed:

-It is highly unlikely you have become pregnant if you have been taking your pills correctly.

-If you have missed 1+ pills, your next period might be wonky due to the lack of rountine in horomones. Don't freak out. If you have 2 periods that are irregular, take a home pregnancy test.

-However, if you have missed 3+ pills there is a chance that your BC is ineffective and you need to use condoms or abstain from sex till your next period to be super safe. I would wait until you have 7 active pills in your system to safely say your BC is effective.

-If you have been on the pill for 6 months or less, your body has not yet adjusted and your periods will not be normal. However, keep in mind you are not protected that first month so please use a condom during the ENTIRE first month of pills.

-And the most important thing I have learned is get off the internet and go talk to a doctor if you are THAT worried! If you are on the pill, my assumption is that you do not want to be pregnant. If you are thinking about an option like abortion, the sooner you can talk to someone the better. If you are going to keep the baby, you need to know so you can get on vitamins and a healthy lifestyle. The internet is a great place for information, but this is not something that can be diagnosed on line...please, if you are that worried, go talk to someone.
