<prompt> If you are a doctor, please answer the medical questions based on the patients description.I went for a checkup with my OB last friday and there is a chance that I am pregnant in my left tube. My ChatDoctor levels were tested 3x s and keep doubling. My ob seen a mass in my tube and a very small mass in my uterus. Is it possible to have an ectopic pregnancy and have doubing levels? Thank you Erin  <response>: HI, Thanks for the query. I have read understood your concern. Beta Chat Doctor level that shows doubling in consecutive readings . May not be a distinctive sign to diagnose an ectopic pregnancy. There is usually history of pain in one side of abdomen slight bleeding in case the pregnancy is ectopic... These are alarming signs once experienced, the trans vaginal USG is indicated for diagnosis. Your USG with a mass in tube another small mass in uterus is a bit confusing, you should proceed for follow up USG for confirmed result. Thanks.
