I had my IUD Mirana removed on November 3, 2009 after inserted on May 16, 2007. My periods have been coming every 23-26 days. This month I started my cycle on January 30, 2010 and it lasted until last Monday the 8th, with just light spotting on the end days. This week I have spotted on Thursday and Friday and now again today with very light cramping. Is this type of breakthrough bleeding normal or is there another cause. We are trying to conceive our second child. In the past trying to conceive my son we did not have any of these symptoms, but I was only on birth control pills not the IUD. My periods then where on mark the tuesday of the 28th day. Should I go in to see my OB? FYI, some changes in my life are as follows: reg. ellipitical work out am, 2 weeks off of all caffeen, and better diet habits.
