so i got a BFP oct 25th confirmed the 27th and was told that I'm 4.5 wks along (due date 07/02/17). Well I had some cramping over the weekend and went to the er this past monday and my levels were at 400 (3wks) I'm being hopeful and stayed calm. Got my levels retested today and they're only at 578. I asked them to be realistic and they sent me to get an ultrasound (vaginal) and there's no fluid, empty sac and nothing in the flopian tubes (not eptopic). She said that the baby isnt developing normally and that if the levels continue to rise but nothing in the sac they will have to give me that shot. I was reading some blogs and people had normal pregnancies, but I'm scared to give myself false hope after today. Can anyone please explain what in the world is going on?
