On the 17th of June, I had unprotected sex but he did not ejaculate inside me. Three days after, i took an ecp but hours after taking it, i had another unprotected sex and also, he didn't ejaculate inside me. On the 23rd of june, I had another unprotected sex and he didn't ejaculate inside me and minutes after, i took another ecp. On the 29th of june, i had bleeding and it lasted for three days. The bleeding has a medium flow and I used pads. Is the bleeding already my period or just the effects of ecp? Is there a chance that i might be pregnant?
