So i'm a guy and i'm just trying to see if i'm mistaken. My girlfriend and i had unprotected sex about two months ago and she is worried if she is pregnant.
The thing is i don't think she is pregnant, but she still has doughs.
A week after we had sex she had her period but she says it lasted only two days(for her is usually five). Then the coming week she started to take birth control pills. She had another "period"(just like before just lasting two days) on the second week after she had her first period. Now this week the 7th after the act she is having symptoms of pregnancy, like breast tenderness, nausea, dizziness, and bloating; but as i have read this could also be side effects of the birth control pill.
She took pregnancy tests at 3, 4, and 6 weeks and they all came out negative. Could she still be pregnant after she having this weird periods, and three negative tests?

Erm before I'd read the bit about the negative tests, I would have said yes, it is entirely possible that she could still be pregnant. However if they are saying no, then I'm thinking the answer is no. Wait and try again later because if she is pregnant the hormones that affect the test will get stronger every day. Also the periods a woman has when she is on the pill aren't real periods, they are created by the pill, so she could still be. Best to get her to have a doctors pregnancy test, or seek some other medical advice x
