I just don't get it...

I need help understanding something. I have irregular periods because of PCOS so I really don't know when I ovulate and how often I do. My fiancé and I found out we were pregnant in early august but found out it didn't last long. 😭😞 I didn't really have symptoms and I only took tests to find out if we were pregnant because of a very vivid dream. Dr blood draw confirmed. I don't really know what ovulating should feel like but I've been having weird things happen lately and maybe I could get some advice. My last period was Oct 16-18. My breasts don't hurt right now but they feel full and thick and usually they are soft and squishy. I have huge breasts so they don't change to often. I've felt more nauseous after eating but only happens about 30 minutes or so after. I have wiped a few times to find very little red/pink blood but nothing on a pad for hours. I've had two separate nights a few days apart where I had brown discharge and then it's gone and not consistent. I've had some minor cramping and last week had minor pain where I believe my ovaries are. And maybe a tickle feeling in the middle of my lower abdomen.

Should ovulation have cramping and slight bleeding/discharge or is it a possibility I could be pregnant 17 days since my last period?
