No ovulation?

I ovulate every month and it's always dead on with when this app says I'm going to ovulate. I taken ovulation tests several months. I always get side pains leading up to my ovulation and have major side pains on the day of ovulation, plus I have painful sex on that day. From what I've read, and what my OB said, that's normal. My ovulation window is ending and yesterday was supposed to be THE DAY....but I've felt nothing! No cramps, side pains, and no pain during sex. Could by ovulation be becoming abnormal? I haven't felt any pregnancy symptoms, I don't think, but we have been TTC for a little over a year.
