Hcg not dubbling

Firstlady • 4 healthy boys after Multiple miscarriages @ 41 praying for my miracle baby 🙏🌈❤️❤️❤️

This morning I woke up spotting I’m supposed to be 8 weeks so I call my OB she said my hug isn’t going up to fast she thinks I’m misscaring but now spotting stopped and I have no cramps

Anyone have this ??
