I didn’t! But my friend who was EXTREMELY active during her pregnancy - ran a half marathon at 36 weeks did. She had an emergency c section. She had approval from doctor
You can try belly band until 6 or 8 weeks . After which you can start exercise gradually
Light walking is beneficial until you’re ready to get into that and Dr approves. Also, keep in mind that if you’re breastfeeding and you start dieting then your supply will go down.
I did, started at 3 weeks as I couldn’t handle no exercise. Just please see a pelvic floor physio to check everything and give you advice
