6 months off the depo

I was on the depo for a year and 3 months and i was due for my shot in October but didnt go back. Anyways i had my first period in February which was my usual 4 days and then i got it again 10 days later for 3 days, now its march and i havent gotten my period at all and ive been experiencing nausea and dizziness and bloating. I have period tracking apps but i dont have much to go off of but the days I supposedly ovulated i had intercourse multiple times that day (unprotected at that) anywaysssss has anyone else experienced the same thing and had a bfp? Ive done soooo muh reading and research oh and ive calculated my conception dates just to have a pregnancy timeline (i know its a little unrealistic) but the 3 dates that i have in mind say that i wont have a BFP until March 21,22,&25 so theres also that. Idk what kind of feedback im looking for here just opinions and experiences
