Taking aspirin

Hihi, I conceived through ivf. Right after embryo transfer, I started on aspirin and found out I was pregnant at about 3 weeks. First scan at 5 weeks, could see fetal heartbeat. Will be continuing with aspirin for the whole of pregnancy. Doctor says it’s due to my pre-gestational diabetes which is a risk for preeclampsia. Aspirin is a preventive measure. I dont have any side effects so far.
