should I take aspirins?

There should be a valid reason why he asked you to take aspirin. For me, i took it since week 13 all the way to week 36, 2 weeks before i delivered. Reason being was i had high risk of preeclampsia, and low dose aspirin helps to prevent blot clotting hence reduce the risk of preeclampsia. I took it for the safety of myself and my baby, and i delivered to healthy baby. You may want to discuss another option with your doctor if you do not wish to take it, he may be able to prescribe something else for you.
