cervix question

lacey
Hi Ladies,
I use a menstrual cup called Femmycycle, which I love but I have had some scares with it (created a suction around cervix causing it to prolapse). I used it today for the first time in a long time and noticed when removing it today to dump and clean that my cervix felt very large and open. I practice FAM but don't check my cervix very often, and never during my period so I don't know if this is normal OR if the cup has "Kyle Jenner Lip Challenged' my cervix. It literally felt like a pair of plumped lips, about the size of a nickle. I'm on my first day of my cycle and bleeding pretty heavy
