"had it for six months. very reliable. insertation is highly uncomfortable but i sucked it up in the end bc i knew it&#039;ll be well worth it for my boyfriend and i in the end. two long (1 1/2 weeks) heavy periods in the same month back in august. two months later had a short ( 3 days) super light period. my periods are now starting to regulate and so far no pregnancy scares. (despite  sex daily and not using any other form of contraception)"
