Ovulation question...

Sammy • Soon to be 21, been a mother to my little man since age 16. I am engaged to the love of my life/highschool sweetheart & we have our miracle girl on the way! Due St. Patrick's Day!
I started ovulating on the 14th. A day before glow says i start ovulating. Tomorrow is sopost to be my peak ovilation day but im having cramps and pains on my left side near the pelvic area. What does this mean?
