Oh mama, I'm so sorry you're experiencing this, it's quite common after C-section, but definitely worth checking with your gynae about because sometimes there can be scar tissue or other things going on that need proper assessment. Since you're only a few months postpartum, your body is still healing, and the depo can also affect lubrication and tissue elasticity in ways that might be contributing. I'd really encourage you to have a chat with your doctor before trying anything else, as they can do a proper examination and give you the right guidance for your specific situation, no need to manage this alone, dear.
