i started miscarrying nearly 2 weeks ago and my blood pressure was 100/56 low..it normally is lowish bottom number 60ish..however yesterday i went to the doctors complaining of feeling dizzy, shaky and faint and she said it would be due to my low blood pressure, she did the reading and it was high...149/89..it has never been above 60s on the bottom number. She was concerned and i need to go back next week. Is it stress? can a miscarriage cause high blood pressure? could they been related?
