Hey ladies I'm new to the menstrual cup and by far I have to say I love it! I'm looking to never use tampons or pads again. I've had a baby so I use the 2nd size of diva cup and I've noticed how I insert it matters.. maybe for me but when I use the 'U' fold and rotate to seal it's perfect I don't even feel it! the next day I tried the 2nd option which is you tuck the top part into the cup and insert it into couldn't get it to seal even with rotating it and I had some serious pressure inside when I stood and walked. so I think I'll be sticking to the 'U' fold! anyone else notice this difference in themselves??
