Slow rising hcg?

Ma

Has anyone had a low but rising, hcg? My first was done last Thursday and it was 77.6, and it was retested on Monday and it was 163.9. I have been having brown/pink light bleeding.

I’m so scared that this means I’m going to lose the baby.

I go back in for another check on Thursday.. so in the mean time. Has this happened to anyone else and they have had a sticky baby??
