Period 9 days late!...

So let me start by saying my cycle has always been irregular. But the last two months it’s been CRAZY. First I had random spotting all month and the next I had almost a month long period so I went to the dr, they prescribed this progesterone pill that’s supposed to regulate my flow ( she said it was basically a deprovera pill with out the birth control part ) but I continued having heavy bleeding until 4/5 after the 10 day pill schedule. Now I’m onto my next cycle and I have YET to start... took two pregnancy test one yesterday and one this morning and both negative. Idk what to do anymore. Anyone go through something similar and what was your outcome? We’re you in fact Preggo or did AF show her face next month? This month is gonna be agonizing 🙃🙂🙃🙂🙃
