Trying to conceive

Hello! I got my birth control depo shot October 27th, 2018. My birth control is due for a new shot between January 12th-January 26th. ( Only had one shot) I was TTC since January 3rd and am lookin to conceive. My period was last on December 17th and now it’s January 15th. I don’t normally track my periods or ovulation. But, I’ve been trying to track. It’s hard to know ovulation and what not. But is there a chance for pregnancy? I still haven’t started my period but aye opinions?
