My history is long and complicated, but the short of it is this:
My cycles are 90+ days long. I conceived my first two babies on my own, despite my OB saying I would probably need help. My cycles used to be 45 days, then 60 days after my first child was born and now they are 90 days since my period came back after my second.
My husband and I have been trying since December, cycles are between 80-90 days long, but my charts say I have been ovulating.
