Girls, who are already in the third trimester, what can you drink for headaches? A blanket, runny nose, my head hurts. They prescribed me something for the runny nose, but I haven't asked about headache remedies. I'm very worried how it will affect the baby, even though they say that the safest is the third trimester and a cold won't affect the baby anymore.
