I've been using a Divacup for a few months with no problems, but recently got an IUD. I heard that the Divacup isn't the best brand to use with an IUD because it has a higher chance of making it expel... I'm looking for another brand which is thinner with less suction? or better to use with IUDs. Right now I'm considering the Lunette but I know there are tons more brands that I know nothing about. Help?
