Hi, my my last day of period is December 8 and I had sex on Dec 17 but the condom broke and took ECP (Postinor-2) about 2 hours later. Tonight at Dec 25 (8 days after ECP) I experienced brownish blood when I wipe, which means it's very light. I have heard that ECP side effects include bleeding within 7 days after use, but implantation bleeding can happen between 6-12 days. Is this implantation bleeding or side effects from the ECP? Please advise on my current situation as I am under a lot of stress, I am not emotionally nor financially ready for pregnancy. Thank you.
