I went to the doctor last Tuesday thinking I may have had a miscarriage. After the blood test, pelvic exam, and ultrasound (both vaginal and abdominal) the doctor couldn't see anything on the ultrasound but my HCG level was in the 6 thousands. I had to follow up in two days. So I went back on Friday and after all the test were repeated. They still didn't see anything on the ultrasound and my HCG level increased a couple of hundreds. They said it could be an ectopic pregnancy but they don't know. I go see my OB/GYN tomorrow. Has anybody ever had this to them?
