Stormy- I was pretty much always very regular. Maybe miss a period once a year. I was annovulatory the cycle before my BFP, and I never actually had a period inbetween, I spotted for over a week which is long for me. Then I ovulated really quickly after the spotting. So just make sure you stay consistant with your BDing, cause you just don't know when you will ovulate. Here are my crazy charts, maybe they may help. When my OB saw them he couldn't believe I got pregnant.
