My hCG has been going up and down for weeks now. This has been the pattern of my hCG since 4 weeks post ovulation: 23 → 55 → 99 → 42 → 23 → 38

I experienced what both my doctor and I thought was a miscarriage and have been going in regularly to check if my hCG was going down to zero. It has now been about 6 weeks of testing my hCG and it has gone down the past few visits but my hCG has gone back up again today. My doctor thinks it may be an ectopic pregnancy so I have an appointment for methotrexate in a couple days.

There is nothing in the sonogram that shows any signs of ectopic pregnancy so my doctor is solely going off the irregular hCG. Has anyone had a similar experience? Does an ectopic have to show up on a sonogram?
