Still no period after miscarriage

Aww, I'm sorry you're going through this. Three months is quite a while, and even though brown discharge can be normal during healing, I think it's best to see your OB para ma-check kung okay lang everything at walang retained products or other concerns, one of my mum friends had something similar and turned out she needed a gentle procedure, tapos nag-regulate na agad ang cycle niya. It's scary waiting, but better to know what's going on than worry, di ba?
