Cycle issues

So this month I decided to start using OPKs. My cycles are typically 33/34 days with 4 day AF. Glow had my fertile week as this week. But I started testing about a week into my cycle to be sure. I have pcos and didn't know if I'm even ovulating. Well I got a positive on 10/31. According to glow AF not due until 11/19 and it's usually fairly accurate for that. However since ovulation I've had light cramping with some pulling sensations. And now I feel like I'm going to get AF within the next day or so. Idk what's going on. I never get it early, if anything it comes late. Although I do have pcos my cycles are regular at this point. Any thoughts? My mind is racing. I was (like everyone else) hoping this was the month.
