I've been having period like bleeding along with clots since two days, however it hardly is on my pad, it mostly only passes when I urinate. Is it implantation bleeding or normal periods? Can implantation bleeding have clots passing through?? Other information- It started off brownish in colour but has turned dark red & red in colour. There are clots. I am sexually active and took an ECP on 18th feb. (Normal period date was due on 24th feb but I got mine on 28th Feb) I also have Pcod.
