I am 5 weeks pregnant and 21 years old. I have an IUD so we went to the ER on Wednesday when I tested positive to get everything checked, my hsg was 400 which they said was low. Got my blood drawn yesterday and my appointment is tomorrow afternoon. They said if it goes down I'm misscarying if it goes up I'm progressing and they will watch to make sure its not Ectopic. I have had wicked diarrhea since Thursday and I attributed it to stress but today while in the shower I bent down to get soap and I stood up and was pulled back down by a stabbing pain above my belly button. Now I can hardly stand up straight. It feels muscular but there really isn't much online about this kind of pain early on. I'm concerned it could be Ectopic or a miscarriage. I don't want to rush to the ER for everything especially with an appointment tomorrow but I'm concerned. I've had mild cramping like my period off and on for a few days, nothing bad and no blood. Thank you.
