I measured my cervix today, and I'm not on my period but I'm pretty sure it will be starting tomorrow. It seemed pretty long; my finger didn't seem to get anywhere near close to the end (although my fingers are kind of short). I'm sexually active and have always worn tampons so I don't really have a problem with sticking anything up there. My flow is usually moderately heavy during the first couple days of my period, and I can go through a super tampon in about 4 or 5 hours, but it does calm down around the third day and is pretty light. The main reason why I want to switch to a cup is I'm so tired of leakage (this happens to me mainly because I don't change my tampon enough), so I definitely don't want anything that's going to leak, and that's going to have a good capacity. I'm pretty petite, about 5'3", 100 lbs, but I'm not sure if that has much to do with anything.
The number of choices in cups is so overwhelming and I'm not sure what brands to even look at. I'm considering a small Diva, large Fleurcup, or large Lunette. These were just the first ones to pop out at me so there's no special reason I chose these ones.
Please help a newbie sister out!!
