I’m 21 weeks. My doctor told me to monitor my blood pressure, even though it has been 120/80 my last two visits (16 weeks and 20 weeks). In the morning, it’s normal 120/82...but my midday and night (I work full time) it’s reading appropriately 133/96. Is it normal to fluctuate? Should I be concerned? Every time I google, preeclampsia pops up. I just started to swell in my hands and I get headaches every so often, but I contribute that to needing to drink more water.
