Is it normal to have constant headaches during pregnancy. I’m just over into my 2nd trimester (about 13.5 weeks) and for the past few weeks I’ve had a headache or migraine every single day. Sometimes I’ll just lay in a dark room and hope it goes away because I don’t feel comfortable taking Tylenol that often. But I work, and I can’t do that at work so I’ll take medicine then. But it wears off after about 6 hours and it’s back. Is this normal? It’s starting to scare me because I didn’t have this problem with my first 2 pregnancies.😞
