I just don't understand. I go to the doctor, my BP is elevated... I go to high risk doctor and my BP is elevated. he admits me in the high risk ward because of accompanied headaches, mild swelling, and a little bit of protein in my urine. also with my last pregnancy, not to my direct knowledge I was diagnosed at the end with preeclampsia, and that is why they took my son by emergency c section at 38 weeks. anyways .. I'm monitored in the hospital for 2 days, the baby becomes tachycardic for about 4 hours and my BP is slightly elevated they give me some meds and he settles as do I. my BP the next day was great... now I'm home and it's elevated again , and I don't know what to do. I just don't want to be admitted. I turned in a 24 hour urine catch to check levels of protein... why can't my BP be good at home?!? am I nuts or something? I feel crazy going and being admitted to seem absolutely fine in the hospital besides chronic migraines....
