i had sex 2 weeks before my period should have came. well i was a week late and the day before i started i took a pregnancy test and it was negative... that was 2 weeks after the intercourse. well i got my period the day after the test and i had normal bleeding for at least 5 days and normal cramping the first 2 days of my cycle. i had sex again right after my period and a month later i took a test and it was positive. do you think it happened after my period?
