Baby aspirin in first trimester?

Hi! I am currently in my fifth week of pregnancy after experiencing loss of my first born at 37 weeks in October. Our placenta pathology report indicate that there may have been ongoing issues with the placenta in the third trimester - fetal vascular malperfusion was found on my placenta and my girl was smaller than anticipated for how far along I was. In my preconception appointment with my doctor she recommended taking baby aspirin. In my first pregnancy, my doctor did not tell me to do so, but given the placental issues in my first pregnancy, this was recommended to me. Has anyone else taken baby aspirin in subsequent pregnancies and, if so, what trimester did you start taking it?
