It will be two years in jan since i have had the mirena. Ive loved it so far. I have always had a period 3-4 days long (it was that way even before i had the mirena.) Last month i spotted for 4 days had sex and it started normally.. not a big deal... this month i spotted for a week no reg flow. Ive had what seemed like ovulation cramps during the spotting. And after everytime i was finish peeing i had a slight pain behind my left hip... i know this alot of information but i just want to rule stuff out.
