6wks pregnant and migraines

Hey Ladies, so tomorrow I will be 6wks pregnant with baby #2 but since yesterday morning I've been suffering from a bad migraine. I've had migraines before that have last up to 2 weeks but I would take prescribed meds for it because regular OTC meds wouldn't help. Now that I'm pregnant, I don't know what to take. Tylenol isn't working for me and I don't want to constantly take it every 4 to 6 hours if it's not healthy for the baby, you know. I never had migraines with the first until after when she was 2 1/2 years old. It hurts really bad, I've tried napping, I've tried putting a cool towel over my eyes, nothing seems to work ☹ And worse part is that none of my family members know about this pregnancy so I can't say anything to them about what I feel
