Yesterday I went to the doctor and my bp was 142/80 which is high for me. I was told my c-section can't be moved up due to hospital policies unless I'm in labor or medical reasons. Well I have a history of preeclampsia and my first pregnancy I delivered at 36 weeks due to protein and bp. I was told yesterday I had a trace of protein in my urine but I always have a trace. I was seeing a specialist this pregnancy as well but was released since my bp was fine during the time and baby was growing fine. Yesterday evening I started having a headache but it went away once I ate. Well today I just got this chronic headache and nausea, which are all signs of preeclampsia like I had last time. I'm wondering if I should wait to call my doctor or go to L& D. Just don't want to hear "it's normal"
