I had unprotected sex on the 28th of may,immediately he pulled out,I took postinor2,I don t know if he Cummed or not. I ve waited but there s no withdrawal bleeding but other times I take it,I bleed some days after except initially when I started taking it,I didn t bleed.I m a bit worried,I feel tender breasts ,pain in the Lower abdomen, white,sticky discharge. Can this be my period coming or pregnancy I forgot to add I have irregular periods
