Pelvic pain question!

Tina
I ovulated on May 19th and I can always tell when I ovulate because my left lower pelvic area where my ovary is, is always tender the day of ovulation. I got a positive opk on the 18th so I'm counting the 19th my day of ovulation. Well, I'm 7dpo, and my lower left pelvic area is tender again. It's usually never tender during pms or when I'm about to get my period but my period isn't due until June 2nd. Anyone know if it's possibly a pregnancy symptom or does anyone else go through something similar? Definitely not ovulating right now.
