Not really sure what's going on 😕

Yesterday at my 36 week doctors appointment, I was told my blood pressure was really high which it never is. My doctor told me to take it last night and again this morning and report back to her. Yesterday I had a headache and some bad nausea which never happens, but other than that I've been fine. My BP was still kind of high last night and this morning, but nothing scary high. I reported that to my doctor this morning and she told me to go to L&D.; My blood pressure here has been perfectly fine like great! But apparently I had some protein in my urine. She thinks she is going to keep me overnight. I've been sitting here for hours on hours being monitored and I just wish I knew everything going on. Like my blood pressure is fine..shouldn't that mean its probably okay? I don't know! 🤷🏻‍♀️
