Scared of another ectopic

Natalie

I had my first ectopic pregnancy in February of this year. Had to take methotrexate and did not lose a tube. We tried again this month and got a positive pregnancy test. Went in for blood work and my hcg was 19 (extremely low) and i had some bleeding. Doc said my levels should be undetectable today but I got another positive pregnancy test today. Has anyone experienced anything like this? I am so scared it is another ectopic and levels are continuing to rise....
