There is an ingredient in ibuprofen that is a blood thinner, which is very dangerous for pregnant women considering we already have extra blood in our system.
Ibuprofen (advil) is NOT safe to take
during pregnancy. Your best be is to listen to those girls who already posted, and drink 2 tall glasses of water real quick. Dehydration is the number one cause of migraine/headache. If after half an hour you still have a headache, take some regular strength tylenol and have a nap. Feel better soon!
