Hcg levels didn't double. 😱😢

Roberta
I'm about 3-4 weeks pregnant and my Hcg levels didn't double in 72 hours, just went up. And my progesterone level went down a bit. My doctor said it might be a very early miscarriage. Did this ever happen to anyone? I'm sooooooooo sad! So worried! She said I can have bleeding anytime now. 😫😫😫😢😢😢
