Hi there
I bled on day 11 of my first IVF, which was black, then brown then heavy red and clotty. it lasted 2 days only, but the result was negative.
This cycle I started spotting on day 7. I was told it could be an implantation bleed as I had a scan and everything looked fine, and didn't show that AF was imminent.
7 days later I'm still bleeding! I haven't had a proper AF, but think the progesterone may have been holding back the flood, but did test

this morning.
I would love to know why I bled so early on too, not sure if it's due to a very efficient body flushing out inviable embryo's, or problems with immune system rejecting them
Take Care, and remember it can be an implantation bleed

luv nat xx
