Stopped taking my BC pills

My husband and I decided to quit my pills only 7 days into my pack and I had a period 4 days later that lasted about 3 1/2 days. 
My question is, how long will it take for my body to kickstart back into a normal rhythm so I can track when I'm ovulating and to TTC? I haven't had a period yet since the last, and that was 30 days ago, when my body was used to a 28 day cycle on the pill. I've been on the pill for 13 years...
Thanks!
