Hcg level rising

Erin

OK long story short… I started bleeding on Sunday thinking that I had a chemical pregnancy. My lines were very faint. Flash forward to Monday my line was extremely visible so I had blood work done on Tuesday which was hCG 29 level. She retested yesterday and I just got the results of 76. They are rising and doubling but still low. Anyone had this experience? I don’t know whether or not to be excited, hopeful or plan for the worst?
