I woke up last night at 2 a.m. with a headache, nauseous, feeling like my bp is a bit high. I have had slight swelling in my feet starting a day ago. Hands feel a bit swollen as well. Sharp pains in my abdomen like right under my rib cage...almost like gas pains but worse. Just not feeling right. I am 36 weeks and 3 days along. Had anyone had anything similar happen?
