I had a D&C about 4 weeks ago and still got a positive test 3.6 weeks after. It made me nervous because my doctor told us to wait one cycle, so she decided to test my HCG and it came back at 8. It made me feel better, but I just took another test and the line seems to be a little darker. Can the brightness of a line fluctuate. I don’t feel mentally prepared to go through another pregnancy I since I was recommended to wait. It is giving me anxiety. I am still waiting for my doctor to explain the results.
