I'm 24 and I received poor advice from a doctor who told me I was covered after only one dose of the pill. ... Needless to say I was scheduled for a D&C a month later. After the procedure mirena was inserted and the first 3 weeks were almost unbearable the pain was debilitating although the bleeding was very minimal. 2 months in the cramps and bleeding were gone, now at the 3 month mark I began bleeding very light pink small amounts but with horrible abdominal pain that comes and goes. The strings were checked twice since I've had it inserted and I was assured it's in the proper place but after intercourse today the pain has increased. Should I be worried or could this just be the start of a period ?
