2 Plan Bs and hot flashes

I took 2 plan bs this week and now I have constant headaches and I’m always hot. Ive never felt like this with plan b before, but Ive also never taken 2 in such a shirt about of time. I constantly feel like shit. I don’t know what to do. I know it has many side effects so is this normal? It’s been like 2 days since I took the last one.
