Headaches

Steph
Just curious if anyone else has started having headaches more often as they have gotten closer to 12 weeks. 
My dr is working with me to see if it's my medications causing the headaches. I'm currently only allowed 1000mg (regular dose -2 tablets split into 2 doses) of tylenol a day and can't take it more than 3 times a week. And well if you have ever had a migraine you know that tylenol doesn't help much at a full dose let alone at only half an adult dose.
