Ovulation question

Kelsey • I have been trying to conceive my second child for two years... I am so happy that it has finally happend!
So let me start at the begging 
I took a depo shot back in June because my doctor dai it could increase my chance of pregnancy after it wore off... 
Well AF never came. So she put me on a 28 day cycle of sprintec (BC pill) to get AF to come. 
I started AF dec.6th and ended dec.9th I started OPK on the 10th and got a positive and also a positive for the 11th and 12th. 
Is it possible to ovulate that soon after AF?
