I had a very rare cervical pregnancy at 6 weeks. It was my second pregnancy, first was perfectly fine. No history of miscarriages. I was admitted into the hospital and had potassium chloride injected into the gestational sac to stop the heartbeat of the fetus. I have been having methotrexate injections and 4 days after receiving the KCL I had to have methotrexate injected in the remaining tissue still dividing. Today my hCg levels decreased from 21000 to 17000, I will be monitored to make sure they get back to zero. I had 5 doses (63 mg) of methotrexate.
