i went to the dr this morning and my blood pressure was high and has never been high my whole pregnancy, i'm currently 35wks and 3 days but just found out i'm measuring a week ahead, the nurse had me lay on my left side and my bp dropped. but i get headaches every now and then and they haven't been bad until tonight and i'm been swelling for about 2 weeks, dr even said my feet and legs are swollen, i'm suppose to call if anything changes. have any of you gone thru this? this is my first pregnancy and i just need advice
