I’m currently using the Diva Cup, but I feel like it is a bit too firm for me. Like it is hard for me to squeeze it hard enough to break the seal to pull it out, so I don’t cause a suction. I have an IUD, so breaking the suction is especially important. Is the Lena Sensitive Cup softer than the Diva Cup and the original Lena Cup? Also, I’m not sure which size to get. The small or the large. My cervix is at a pretty average height, and I have a heavy flow. I just get super picky and worried because of my IUD even though I haven’t had any issues with it.
