Chemical Pregnancy (tmi in some parts - no pic)

So I got faint positives which obviously went away since I have my AF..my AF is usually heavy for 2 days then tappers into very light. But this time around I'm clotting, but these are huge clots and I'm still at a medium flow and it's suppose to end tomorrow. Do you know if AF lasts longer because of the chemical or if that's why I'm clotting so badly? Thanks in advance 😳
