Last week I was diagnosed with an ectopic pregnancy in my left fallopian tube. I was having heavy bleeding and severe left pelvic pain. Highest HCG test was around 280 and they then gave my a shot of methotrexate. One week after methotrexate my HCG is 180 and am still bleeding quite a bit. How long did it take others for HCG to test at zero? How long before ttc again?
