Hello everyone! I wanted to ask when you started exercising after giving birth? After giving birth, they applied both internal and external stitches to me. I even tried to go to the bathroom! It's been 3.5 months now, but I still feel pain near the forehead area, and it seems like this is from the fact that my buttocks, pelvis, and abdomen muscles weakened ( What would you recommend?)
