Mirena IUD out in June. The doctor said it could take up to a year so I started my journey disappointed. And instead of my cycles getting closer together (normalizing), they were getting further and further apart. From 45 days to this last excruciating 73 days, and countless bfn's. My test was still reading negative on day 65. Needless to say I thought this test would certainly be another negative. And it's faint, but for sure there!!! All in all it took four cycles, which was 7 months for me.
