I'm just curious about the chances a woman would have to become pregnant if she had unprotected sex and then..

Question

started her period a day later as usual with no changes to her normal flow. And if she was pregnant, would she already show signs less than two weeks later? Me and my friend were debating this and I'm on the side that she couldn't be pregnant and less than 2 weeks is WAY too early to have morning sickness or what not unless it's a "phantom pregnancy". :D

Answer 1

The chances she could be pregnant are extremely slim if she had a normal period following the sex. If it was a light, or an abnormal period then the chances are even higher, because it may have not been a period at all. It may have been spotting which can occur with ovulation, or break though bleeding.
Two weeks after sex is not to early to experiance pregnancy symptoms, even morning sickness.
Have her take a test to be sure.

Answer 2

No, she wouldn't be pregnant. Because that flow is what would have had to received the sperm. There is no other flow that will be in her body until at the earliest about 10 days after her flow begins so there is nothing in her body right now to allow her to get pregnant.
