Absorbed Pregnancy

If you had an ectopic(tubal) pregnancy, is it possible/likely that your body can absorb it? I could be anywhere from 11 to 8 weeks along, and I'm not having any sort of (what I thought were) symptoms. I have my first real Dr's appointment next Wednesday. The only thing I've had was two positive store tests as well as a positive pee test from a clinic. These tests we're taken about a month ago, but no blood test has been done. I feel like there may have been a rare different reason for my higher levels of HGC that wasn't a pregnancy (I have never taken a pee test before, and in some cases thyroid issues can cause a positive test with no baby). Also, I was having sharp pain almost on a regular basis for a while in my lower abdomen. I don't think it was normal cramping (which occurs for some at the beginning of a pregnancy). That symptom hasn't happened in over a week. But I was worried that the pain was due to a tubal pregnancy, which makes me wonder if my body could have taken care of the problem before it was one? If you have any insight, I would appreciate it so much!! I have more questions than answers and it's not a fun place to be.
