Depo shot experience?

I was on the shot from feb 2020-Nov 2020 after having my second child. The last dose I got was back in November. I started getting my periods back in may of this year but it has been irregular. I have not yet gotten my period for the month of August and had a neg pregnancy test. Anyone experience the same thing or anything similar? I went on 10 mg of provera for 10 days which did nothing. I keep overthinking that something is wrong and I can’t get pregnant 😢 I’ve also started recently TTC (about a month now)
