Faint lines and then BFN

So I’m 11 weeks post mc. Af came over 3 weeks ago so I know I’m okay there.

I’m now getting anything between a few days of BFN, not even a smalll vvvvvvfl to continuously vfl that are very visible.

Did anyone else’s HCG after mc fluctuate up and down? Looking for advice from people who have experienced this... especially at 11 weeks!

I don’t have any retaining tissue as this was cleared through a D&C; and checked after via ultrasound
