Cup leaking= wrong cup type or inserted wrong?

Tara

So I just had my last baby 5 months ago and figured this month would be a good time to go back to using my diva cup. I had issues with leaking before I was pregnant but it was just spotting. Now I'm leaking even more and it feels like The cup is almost sliding down too far and is uncomfortable! I have a weight for kegal excersizing and maybe if I did that I wouldn't have the same issue?

I was just hoping someone could tell me if I'm inserting it wrong or if it's simply not the cup for me!

Thanks!
