I have just started with one too! Second cycle just done and I must say it was awesome. First cycle sucked as it seems I needed to trim off the stem entirely. I tried it on the first day and even with a shortened stem it was soooo uncomfortable. I gave up for that cycle, but this time around, without the stem I am absolutely converted. I so wish I had come across these sooner, especially since my flow seems to be so much faster and heavier after babies.
Thanks for all those who offered advice here. This thread and some other sources were fantastic!
