The FemmyCycle website says it's safe to use with IUDs. For removal, they just say to pull on the loop. Is this the best way to do it if I have an IUD or do I have to break suction? It doesn't have any suction holes...not sure how this works, but I don't want to mess up my IUD. I have a SUPER heavy period and tampons soak almost instantly and I go through pads like crazy. This seemed like the best cup for me and one that says it's safe for use with IUDs...Any advice or tips?
