low blood pressure

This pregnancy has already been so much harder than my previous ones and it seems to keep getting worse. I am only 8 weeks and have felt so sick since the minute I got a BFP. Besides an initial visit at 4 weeks where the doctor only did a pee test to make sure I was pregnant, I have had no blood test or ultrasounds or really anything. We are having issues with insurance. Anyways I've been watching my blood pressure lately , yesterday was low but today it's extremely low for my usual. It was 83/50 about an hour and a half ago. I have a migraine, dizzy, and just feel awful. I am hydrated so I don't think that's it, I am also anemic if that matters. Any one have to advice or think I should do something?? Help!
