HSG and early O?

Hey ladies, I had my first HSG done Friday 5/22(CD5). All looked good. The left tube was being a little difficult but finally cleared out and the doc was happy with results as was I!...I typically have a 25/26 day cycle with ovulation around CD14 or at least that's what the OPKS tell me lol. This past Sunday I had pinching like cramps on my left side (which I usually get when I ovulate) so I took a opk and it was negative...yesterday I took one around 230 pm and it was obviously positive..I was only at CD 9. Is this normal?
