First of all, u should look for other signs. But if ur truly worried get a urine test (u can get them for around $1 at a dollar store). And they can show false negs sometimes so maybe a blood test from the doc. Its not extremely common, but yes u can have ur period while preg. I knew a girl once that it it for the first 2 months.

Its been a mounth sence we last did it she had her period and all she's had is chese pain isn't she suppose to show more simptoms if she is pregnant?

Not nec. Some women don't really have signs until 2-3 months along.

I apologize, billy12, for being an fool, but what is "chese" pain? The first thing that popped into my head is chest pain, which I have never heard of as being a symptom of pregnancy.

As for the whole periods in pregnancy thing...It's definitely not common, but it can happen in some cases. But there's noticeable differences in the flow...It could be a lot lighter than usual, or be more mucous than blood. Cramps may disappear. Granted I am not sure how a woman could have a full-blown period during pregnancy, seeing as the menstrual cycle is a shedding of the lining of the uterus, and if you shed that lining when an embryo has implanted in it, it's going to go "bye-bye" with the lining.

Consider this question (forgive me for being a bit rude and personal): is your girlfriend usually a light "bleeder"? If so, then a change in flow may be hard to notice. But if she bleeds moderately to heavily, then you'll definitely be able to tell what's going on.

Ask her if her period, though on time, was lighter, or if she noticed any changes in it.

....................

A final thought...If she's experiencing any pelvic/ovarian pain out of nowhere, don't automatically assume pregnancy - it could be something like endometriosis or ovarian cysts.

............

Keep this in mind: some women may experience every symptom of pregnancy known to man and not be pregnant, and others may feel no changes and be pregnant.

As someone said, the only way to find out is a test. The urine tests are not always reliable, but blood tests are foolproof. You can either ask her doctor or try and find a family planning clinic in your area to do confidential blood tests for her.

..............

Best of luck to you and your girlfriend, and I hope things work out in your favor.

My friend is pregnant and still getting her period and I read that a woman was pregnant with twin and still had her period the whole time. She don't have any cramps when she gets it and it is pink and not the normal flow. It is also has a lot of discharge in it ( sorry if I grossed you out). Here is what the woman told me:
"yes I was 12 weeks pregnant with twins and still had my period and my mother was on her period the whole time she was pregnant with my little brother. So yes it is possible. "

Ok...I dont understand..How can u get ur period when ur pregnant if ur egg is fertilized? It makes no sense..Like I had my period 2 weeks ago..It was normal..Really bad cramps and very very heavy..*like usual* but im having all the signs of pregnancy...Im sooo confused!!!

my frendsz say that my stomach got bigger nd rounder nd i been feeling mah stomach and yuh kno iitsz kinda hard buht i got my period 2dai so0 dooes that mean im not pregnant.????

Scaredbaka, you make interesting points in your post however, a woman can have her period AND shed her lining (not the baby per se) while being pregnant. I know because it happened to me. My obstetrician explained that it's your body's way of cleaning out the uterus/womb in preparation of the 9 month occupancy of your baby. So yes, it can happen. By the way, did you get an answer on what "chese" is?..too funny..go figure!
