I'm now 13 weeks and have only had the one migraine thus far (thank god!)
I took panadine and caffeine (it helps the blood vessels settle down in your head). But mostly I've been just taking panadol if I can. Normally it does nothing at all for me, but I'm trying to get to the headaches at the very beginning to cut them off before becoming migraines. Panadol also comes in osteo, it's 650 instead if 500 paracetamol. It's the in-between step to taking panadine. I checked with my OB and midwife about the panadine and was told it's fine, tho if I can avoid it I will.
Migraines suck, I really wish all my fellow suffers all the best of migraine free pregnancies!! Xx
