I was wondering, can you still be pregnant, if your period comes? a regular period that is, not a light one.

User avatar You cannot have a period and be pregnant. let me explain why.

Typically, a womans cycle is a month long. Around day 14 of her cycle, ovulation occurs. Meaning, she releases an egg for fertilization. This egg lasts only for about 2 days, and sperm can live in the body for about 5 days, so the week before ovulation occurs can be a fertile time. The next 2 weeks of a womans cycle her body is preparing for pregnancy, assuming that the egg was fertilized. The lining of the uterous thickens, preparing itsellf for implantation of the fertilized egg.

If no fertilization occurs, at the end of the cycle, a woman has her period. The bleeding is caused by the shedding of that thickened lining, because it no longer needs to be thick, because there was no egg implantation. If however, fertilization occurs, and pregnancy happens, the lining of the uterous stays thick, and implantation of the egg occurs. Since the lining did not need to shed, there is no period.

However, sometimes women experience bleeding during early pregnancy that they mistake for a period. Generally however, if a women is pregnant and does have bleeding, it is much lighter than a normal period, and does not last as long.

If you suspect pregnancy, the first step shoudl be a pregnancy test, and if you get a negative result, followed by a period, it is very safe to assume that pregnancy did not occur, and you are safe. If a pregnancy test is a positive result, and a period still occurs, then you shoudl see a doctor to confirm that you got an accurate test result, and confirm the source of the bleeding.

So the short answer is, no, a woman cannot have a normal period and still be pregnant, but some pregnant women can experience bleeding that is indistinguishable from a period.

so in that case, if her last period came on january 13, and then it never came on februrary 13. Does that mean it is almost impossible for her to be pregnant on Februrary 23? If we go buy that cycle, its 16 days in, which would be around the 29th.

Oh btw her period came on april 7.
