Trying to conceive

Maya

So my last shot was last year in the month of September 2018 & it’s been 12 months without any depo what’s so ever and I’ve started my period again in a long time (July the 11th ) it was pretty irregular so 4 months go by without a period ... my second period started I can say this month November 2nd or 4th (2019) and lasted a week I’m actually coming off my period today moral of the story is if my periods are irregular and even if I’m ovulating which I have started back ovulating can I still get pregnant ...???? Say for an instant if I have sex on the day I’m ovulating or see it then have sex right away can I become pregnant??? I’m ttc😩😩😫😫😫😫
