My numbers finally came back- not good news

Sa

At 12dpo my HCG level was 55. Just got my draw back at 15 dpo and it was only 92. It didn’t even double in three days :( has anyone ever had this and have it be okay? I’m completely shattered by this news :(

Update: the number came back at 112

Update #2: my last number came in at 37. So it’s officially ending in MC.
