"normally i have a 3-5 day flow with cramps/back pain for 2 days. after a pregnancy scare i decided to get this iud put in. insertion was a bit more painful that i anticipated and i had some bleeding for a day or 2. i&#039;m now on my first period with it and i&#039;ve been having some form of bleeding for 10 days now i am extremely frustrated. i did read that periods may be heavier/irregular for the first 3-4 months. i suppose i mentally anticipated a heavier flow rather than a normal/lighter flow for a longer period of time. i would much prefer the former. i have cramps everyday now for about an hr or 2 and even when the flow darkens i get cramps and back to bright red blood. it feels like i&#039;ll have my period forever. will update"
