During my first 12 weeks I had migraines on & off. My ob recommended tylenol & fluids. It didn't help much. My blood pressure was fine, I was miserable. I hope you feel better soon!
I read that headaches are common. It could be from hormones. I would try and drink more water and get enough sleep too. I wouldn't worry about it though. I have had a headache for two days as well. You can take tylenol.
I had lots of headaches early on, could be dehydration or like me you may be suffering more because of your sinuses. I had read that ladies have sinus problems when pregnant but this is the first time it has happened to me (I'm on baby #3) I'm still blocked up now and again but the headaches have eased (I'm now 26wks).
I just had the same problem I had an awful headache for 3 days...i'm 33 weeks...I thought it was fine and would just go away but someone on here told me it could be serious and to call the doctor or go to the hospital..I went to the hospital and they said i'm dehydrated..it could also be high blood pressure or out could be nothing..I would call your doctor if you can.
