HEAVY 2 DAY BLEEDING WITH BLOODCLOTS AFTER SEX

Hey!

So two days ago I had sex with my husband and I ended up bleeding after we were finished. Didn't think anything of it as it can happen from time to time.

But the next two days were hell, I had a heavy flow and even blood clots. It has seem to have stopped now and according to clearblue I'm not pregnant.

Despite the fact I'm not due to have my period til the 15th earliest and my last period was ended the 22nd and it was my standard cycle.

I seem to be fine now, but I'm just a little concerned about it all.

Thoughts?
