I read online that headaches in the third trimester...especially really bad ones, could be a sign of pre-ecclampsia. After having the same headache for 3-4 days, I finally went into triage at the birth center. Once there, they checked my BP. It was 140/90, but went down slightly while I laid in the hospital bed. I remember one doctor coming in and asking point blank what type of pain killer I wanted. I told her I didn't want any pain killers. I just wanted to know if I was going to be alright. They didn't draw blood, or even check my urine. They just sent me home with an anti-anxiety pill that I never took.
The last few weeks of pregnancy I kept a close eye on my BP myself by checking daily at a local pharmacy. It stayed pretty consistently in the 130's over 90's. My hands and feet also swelled up and I couldn't fit any of my rings on my fingers anymore. My midwife was concerned, and finally checked my urine ONCE (no protein), and took a blood sample which turned up nothing concerning.
My water broke on its own at 39 weeks. We went straight to the birth center in the hospital, and got directly into a room. They checked my BP, it was 150/100. My midwife ordered another blood panel for Pre-e. In the meantime, I gave birth quickly and naturally to my beautiful baby boy. He was born full term and completely healthy. I remember them putting him on my chest, and I remember holding him for a while and staring at him....then my memory gets fuzzy.
