birth control
"Had it for six months. VERY reliable. Insertation is highly uncomfortable but I sucked it up in the end bc I knew it'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)"
