I'm 17w4d pregnant and I've already been to the ER 2x since. first time for bleeding that only lasted a day second time for really bad abdominal cramps. both times I was sent home cause baby looked fine. But one thing that has been recurring is this feeling I get when I stand/walk for too long. it's like I need to sit down immediately or I feel I will faint. happens to me sometimes at my job (which I stand consistently for 4 hrs) and I recently mentioned it to my OB after my second visit to the ER and she paid it no mind but it really has me worried. I want to go to a different hospital for a different opinion just don't know if I should don't want to waste my time. oh and this is my first baby
