I’m really anxious to test...

I was diagnosed at 13 with PCOS. My now fiancé & I have been trying for a while & no luck. I stopped trying, keeping track & worrying about getting pregnant after the last time I thought so. My last period was 8/29/2020 & I had been having 30 or so day cycles before then. I spotted a few times in Sept & like once last month, I thought my period was gonna start both times; I even tested with a dollar store test but it came out negative. Now it’s 11/3/2020 & I woke up this morning & my back was aching soooo bad, I couldn’t get comfortable no matter what I tried. I’ve also noticed I’m feeling actually hungry which I don’t usually & my boobs have been sore up into my armpits. Have any of you ladies had this experience or similar ones & been pregnant?
