12 weeks pregnancy

My doc prescribed me with aspirin too cause I had post-delivery complications for my first born. I had pre-eclampsia. And my first few appts for my 2nd pregnancy now I had high BP so was advised to take aspirin to prevent blood clotting and lack of oxygen to baby. I’m 20weeks now and started at Week 15 and I’m 34, obese and had protein in urine during last appt. Best to take if it has been prescribed for you. Only stop if doctor says so.
