Pregnancy after ECP. I had unprotected sex 2 days after my period and he came inside. I took ECP and after 2 weeks got light bleeding, after 5 or 6 days we had another unprotected sex after and same he came inside and i took ECP (whenever I took it,its just 2 hours after the sex) and now I am pregnant . I just want to be sure, is it the 1st sex that we had or the 2nd time? Is the bleeding after the first ECP period or just hormonal effect? Thanks
