AF every other week.

When I first got with my SO,after a month or so, Mother Nature started showing up everyother week. I had an IUD at the time. Had had it in for two years prior with no problems. He said it was my bodies way of trying to get pregnant. Lol. Has anyone else had this happen?  I never went to the doctor. He moved away and I went back to normal monthly cycles.
