I had a failed IVF cycle recently - my period came only 7 days after day 2 transfer of 3 embryos. This was 13 days ago. For the first 3-4 days it was an extremely heavy period with actual pieces of tissue coming out. then it tapered off until at day 6 I thought it had stopped. Day 7 I got another big rush of bleeding and since then I have been continually spotting heavily enough to need a small tampon. I am now on Day 14 if you count the day I got my period as day 1 and still bleeding. What is wrong with me?!
