Migraine help!

Please if anyone could help I would greatly appreciate it, I recently found out I was pregnant (about 4 wks) I haven’t been able to go to the doctor just yet, but tonight I had such a terrible migraine, and after trying literally every trick in the book, I was in so much pain I had to take an Excedrin. I’ve had migraines all my life so it’s nothing uncommon to me, but idk how I can even get through this without excedrin, it’s been the only thing that has ever touched my migraines and I’m really worried that I’m going to hurt the baby.
