Blood clots?

Crystal
Hi ladies I had a miscarriage last December around maybe 7 weeks I had a blighted ovum and then a miscarriage and after I started to have the miscarriage I had blood clots and quite a few probably the size of like 2-3 quarters. I'm around 7 weeks now and I plan on going to the doctor around 9 weeks should I take baby aspirin to prevent blood clots or wait til I goto the doctor ?
