Hey mama, after 3 months CS at walang regla pa, light spotting or minimal bleeding during or after intimate time can happen kasi the area is still healing and sensitive pa, pero if it's heavy bleeding or may foul smell, better check with your OB agad, okay? A few of us moms from our circle experienced this din and pag tinignan ng doctor, naging okay lang after getting cleared, so don't panic but don't hesitate to get it checked para sure.
