Gynae advises to take Aspirin throughout Pregnancy

Hi, I went for my routine check during week 10 and the gynae at KKH has advised me to take a dosage of Aspirin from week 11 onsqarda and to last throughout my pregnancy. This really puzzled me as I have no history of high blood pressure and heart issues. The gynae said taking Aspirin during pregnancy is to prevent complications in getting high blood pressure / stroke. Any mommies out there is taking it? I don’t feel comfortable taking it. After all it’s a Medication and I’m afraid of getting side effects.
