I live with a constant headache every day since I was about 12 weeks. I'm 18 weeks now. Its it terrible.
I had the same thing right when I was around that time. My doctor told me it was due to estrogen withdrawal because your hormones become way less present around that time. I don't really think its a huge deal but if you feel nothing is working then yeah I'd go to the doctor because there is a chance that its something more serious
You May have to go to the emergency room and get a shot. That's what my nurse told me to do if the Tylenol and caffeine didn't work. I hope it goes away soon. I feel your pain. I've had a headache almost everyday this week!
