[|AI|]  Hello and welcome to Chat Doctor. Early pregnancy may naturally have periods of episodic vaginal bleeding with clots. This is caused as the baby with the sac in early pregnancy is too small to fill up whole of the uterus. The exposed inner lining of uterus may degenerate and bleed just like a normal menstrual cycle. I am assuming that your ultrasonography after the gush of bleeding showed a live baby with evidence of fetal heart beat. In that case chance of abortion is minimal. ASA or aspirin tablets are given in pregnancy to help in free flow of blood between mother and fetus. Please write back if you have any more queries.
