Nurse told me "Not looking too good"

nicole • Have beautiful rainbow baby identical twin girls 🎀
I've been in and out of the clinic getting blood work every other day for over a week because my hcg levels aren't doubling like they are supposed to. Had blood drawn again this morning and the nurse tells me they still aren't doubling so it's not looking too good. I'm trying to stay positive and not stress but after hearing her say that I'm so scared I'm going to lose this baby :(
