Doctor prescribed aspirin to me. I'm not sure if I should eat as the side effect is nauseous

Please check back with your doctor about the nausea before you stop taking it, especially since it's prescribed for you during pregnancy. They might suggest taking it with food, or switching to a different option that works better for your body. Don't skip doses on your own without asking them first.

aspirin is not a supplement. Hmm your gynae should have advised you what's it for right otherwise why prescribed to you? The side effect is nothing compared to the risk of having preeclampsia which could affect both you and the baby
