BFN...AF due in 2 days

Harmony • 38, DH 51, 13yo boy, 9yo girl 10/21/17 👼🏻6w5d 🌈👶🏻 boy C-section 10/12/18

I had a miscarriage on 10/21 at 6w5d and my beta was less than 2 last Friday. I'm feeling nausea, slight headaches, lots of bloating and gas, mild cramping occasionally...this is not normal for pms for me though. I didn't use FMU. Will test again with FMU on Sunday. 🙏🌈👶🏻
