"about 6 months in i began getting a little moody, but didn&#039;t think much of it. my periods have begun to get really heavy and i never know when they are going to stop or start. sometimes it will last 4 or 5 days and sometimes i&#039;ll have my period for a month straight. my mood swings are absolutely terrible lately and i&#039;ve  had some depression (i&#039;m generally a very happy person). i have headaches regularly and have pregnancy symptoms all the time, such as sore breasts, spotting, bloating, and nausea. my boyfriend and i have barely been able to have sex because of the almost constant period, so no wonder you don&#039;t get pregnant! and my sex drive is much lower after getting it inserted."
