I had a blood clot in uterus but outside the baby sac too. It was detected during my 12th week scan. I didn’t experience bleeding either. Doc prescribed progesterone vaginal insertions to stabilise pregnancy and I did so for a month, then I noticed super dark brown to black discharge (not a lot) after. Went back for a scan and baby is healthy. I guess it is fine unless doc says otherwise! My doc didn’t mention too much of it too.
I had it too during my 5th week.. then doctor gave me duphaston for 2 weeks... then the clot came out by itself on 8th week.. I thought I had a miscarriage.. then I went to emergency to get checked and everything is fine.. as long as it is not inside the sac there's nothing to worry I guess... I already gave birth last year July 🤣
