Belly bandit?

Samantha • Mommy to 2 beautiful little boys - toddler and newborn. 💙
Have any of you used a belly bandit? I'm 2.5 weeks postpartum and just started wearing mine yesterday. Today I noticed I felt really crampy and my PP bleeding went from merely spotting to much heavier and clotty. Has anyone else had a similar experience? Should I be concerned?
