Near the end of my period, my cervix drops lower and changes angle slightly and I have no issue suctioning to cup to my cervix and it staying in place. However, when it's higher up at the start of my period, I put the cup in, pop it open, put it in position around my cervix, making sure my cervix is inside of it not to right of it, and I'm pretty sure I feel it suction properly (I'm still a noob and the fact that it stops working makes me doubt myself, but I push the side in to let air in, pull it down, then kegel as I push it up, twist it, all that jazz. I feel the rim and it seems very well in place).
However, when I go to take it out because I'm leaking, I find it's migrating to the middle of my vagina, leaving my cervix outside of it on the right. Is it possible for a cup to loose suction and shift (maybe since it tilts to the right a lot, pressure from the right wall of my vagina on it when I move makes it lose suction?)?
I was thinking, maybe I need a cup with a wider rim? Maybe that way it will sit up and encloses both my cervix and the empty space to the left of it (I currently have the small size cup, I'm 18 and have a fairly petit build).
Any help would be greatly appreciated!!
