If I had unprotected sex on may 10th, I just took a pregnancy test today... it came out positive. Me and my boyfriend broke up about 3 weeks ago.. and I had sex may10th... is this possible?

What type of test did you take ? It is rare a test would show up post after 5 days.

Did you have sex two or three week ago also?

If the test was not from the doctor, you will want to go and verify this with your doctor.
