Bleeding 5 days before predicted period.

TTC for over 2 years, last month found out I have a blood clotting disorder that has caused us to have three miscarriages so doc put me on baby aspirin. This month we tried hard (or more often) than ever before. Now I am 5 days before my predicted period and I starting bleeding either a light flow or heavy spotting. Doctor said it just sounds like my period but I have never had a early period before.

Ugh is the only emotion I have right now. Any insight?
