Pregnant or AF?

So I skipped a period then ovulated on day 32, according to opks. I took a hpt to see if I was pregnant but it was negative. Since I've ovulated my nipples have been sore (about 2 weeks now) and I've been having more breakouts than usual. I do breakout before af but only a few days before. I've been having it for over a week. Getting breakouts here and there. I've also been getting headaches. I hadn't experienced any nausea or any other symptoms that could be pregnancy so I'm not sure if it's that or just my AF coming soon. What do you guys think?
