I am a newbie on the TTC world, DH and I barely went from WTT to TTC 2 days ago. I have no idea how to start charting or checking for ovulation or what not, and this is why I joined BnB, to get answers. According to My Days app I should be starting my period tomorrow. I wanted to know what this whole cycle talk is all about, does it mean that a cycle starts when the first day of your period starts?? So when people say they are on cycle 15, does it mean 15 months?? =)
