Anyone else practice this? I want to go off the pill as I think it is messing with me and I would like to go chemical free for a while. DH and I would like to TTC mid next year for 4th and final baby, after which he will get a vasectomy. But I don't want to stay on the pill for that long...so does anyone have experience with this method of contraception? I do have a fair idea of how it works...just want to hear some thoughts, get a bit of feedback!
