No period(s)

I'm new to glow but love the support community here so I thought I'd ask for some help. My last period was November 12th and I haven't had a period in December or this month. I am still on birth control and have taken a few pregnancy tests just to make sure. My husband and I aren't planning on starting to try until next month. I just don't know what to do for the <a href="">period tracker</a> since the last one was in November. I can delete periods off of each month but it wants to put in a period again a week or two later. Since I'm on birth control, I know my period was to come this past week and I won't be getting it this month since I started my new (and last) pack today. How does  this app help with irregular gals such as myself?
