Okay ladies! I need your help. Never in my life have I tracked periods. I was on depo for 8 years and finally came off of it, Sept of last year (2014). While on depo I never had periods, but within the first month of coming off I started my period, and have had one every month since. I started tracking in Jan of this year. My period start dates are as follows- Jan 9th, Feb 16th, Mar 17th, April 10th, May 8th... would you say that's a pretty regular consistent period, give or take a few days?
