⚠️ TMI Can someone help me please ?!? TMI

The past week I’ve been having bad cramps and clots of this red chunky stuff. I had an abortion on the 5th of Dec, but I stopped bleeding since then. I also got onto the birth control pill I think 3 weeks ago & I’ve been spotting a little bit nothing like these clots. I only get the clots the day after sex. What is this ?
