I used the Nuva Ring, i thought it was great, you dont need to remember to take it(i use to forget to take the pill) i used it for about 20 weeks but in the end i was told by the DR to use them constantly for 9 weeks then have AF as my AF started coming every 2 weeks, it doesnt control AF like the pill does, it is for contraception only(well thats what my Dr told me), you cant use it while Breastfeeding, umm what else lol, you can leave them in or take them out while making love

they are expensive but that is because they are new i think i paid $60 for 3rings(i was also told the more people that buy them the cheaper they will get)
