So, I get severe headaches and migraines ever since I was a preteen. I'm 22 now, so I take Tylenol 1's A LOT. I recently found out I'm pregnant, based on my last period and the length of my cycles I should be about 4 weeks in. Im not taking them anymore, but I'm just wondering if this could have affected the baby etc. I'm pretty worried and I haven't made a doctors appointment, I just found out this evening. So I have to wait till tomorrow to see a doctor. Anyone else take Tylenol 1 before knowing, and if so we're your kids alright?
