Depo shot troubles... Ugh TTC

Happi

So we are ready to TTC and my last shot was Dec 2015. Finally started my period June 2016 started off very irregular. 3 days then 4 days. Then finally got on a 28-29 cycle some periods lasting 5 days or 6 days ( very normal bleeding)

However i dont think im ovulating some months? No stickyness to go by. Ughh

Just wondering how much longer until im back to normal from being on this shot for a very short time of 1 year Dec 2014 to last shot Dec 2015 ( that was only 5-6 shots taken) ughh. Very frustrating.
