Migraine

So disappointed. I had a migraine yesterday and felt so beyond awful that I took a Rx pill before hearing back from doctor if ok. He, of course, said not in the first trimester. Meanwhile, the migraine rebounded in the afternoon. By 12:30am I caved and toon another dose. No choice. My research online seems to indicate no risk, they just don't green light it "in case". Others say ok if necessary. Just feeling concerned and guilty. Ugh. My husband reassured me that people do a lot worse in pregnancy and have healthy babies.
