One great piece of wisdom someone here gave me: when we first started using tampons there was a learning curve so give yourselves some time to get used to the cup. I'm just sorry I didn't know about this sooner! (like 20 yrs ago sooner)
As for the tipped cervix: mine is also tipped. I bought the Instead since I'm pretty much done with my cycles (yippee!!). If you still feel like you just can't seem to get the Cup to work for you, try the Instead instead! (ain't I the clever one!) You don't need to spin it and - although the instructions say use and toss - I rinse mine under hot water just like the Cup and reuse it, 1 per cycle. That way instead of a million tampons I have 1 cup. Instead is available OTC at any drugstore.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
