Another specific activity I've had trouble with is singing. I sing in a band and when I really sing loud, my stomach and pelvic floor muscles push out and down. It makes the cup slip down, no matter what I do! This makes me really wish I had a different brand or size.
Also, if anyone has a link to info about getting to know your cervix location, that would be great. I have a feeling mine is low.
Thanks in advance!
