I was supposed to get a confirmation of pregnancy and an ultrasound to date the pregnancy Wednesday. I lost my OB recently so I just made an appointment at a local clinic for the confirmation. After the positive test the proceeded to the ultrasound, and she got worried. She asked her supervisor to look at it. I was told the pregnancy was in my fallopian tube, she said it was dangerous and I needed to go straight to the nearest emergency room. I was devastated, after two miscarriages, it was so rough. I spent the next six hours in the ER running multiple labs, and 2 more ultrasounds. They came in and told me after the nurses there had me sedated, that it looks like a cyst in near my ovaries and I AM pregnant but it's an unknown location, most likely due to being so early along. I've been tracking and TTC for over 6 months but my ovulation varies so no clue how far along I was. At the hospital that day my HCG was almost 700, we re-ran the test yesterday ave its at 1800. I'm going in next week for another ultrasound, I'm so nervous, idk how many more losses I can see. Has anyone else ever had something similar or a pregnancy in an unknown location?
