Headaches

I'm 9w4d and I've been having headaches often. I know Tylenol is suppose to be safe but I've read new studies that show more kids with ADHD had mothers that took Tylenol while pregnant. I'm sure you'd have to take it regularly for that to be close to true but with this pregnancy I just decided I wanted avoid everything including over the counter medicine. (Since I had a miscarriage last year I'm almost scared to take anything)  Does any ladies have advice on what I could do to help ease them?
