Migraine...what can I take?

Amnesty • Mommy to Aurora born at 31w2d, Declan born at 37w0d and Connor and Liam due 1/31/2018.
I feel like I may be pregnant but so far just negative tests. The only thing that works for my migraines at this early stage is excedrine migraine. Is it safe to take it? I would like to catch it before full on pain sets in.
