Another been there done that chiming in! Follow directions and you and the baby will be fine. We were able to delay delivery until about 6 weeks before my due date...both mom and baby were fine. I gained 90 pounds during that pregancy, 60 of it came off in the hospital due to finally losing the retained fluid. Before I delivered I looked like Elvis in the later years, LOL!
Best wishes. Hopefully since you aren't spilling protien, the elevated blood pressure is due to nerves and nothing else.
