Any other mamas?

I’m 35 weeks pregnant & went in yesterday for a routine OB appointment. I had high BP a week ago when I was seen at the hospital for sciatica nerve pain & was told to follow up with my dr. Well yesterday comes & they do my bp twice & it’s elevated again. So they test my urine & find protein in it. Blah blah blah- I get sent to the hospital me & baby are monitored they do blood work & my blood work comes back fine. Basically what I got from it is they believe I am going to develop preeclampsia/am developing it but there wasn’t enough in blood work to diagnose it yesterday. Has anyone else had this happen?
