ovulation cramps

Hi I'm on day 19 of my cycle. I took my last clomid pill on the 30th September. Saturday I ended up having slight twinges in my ovaries but no Increase in cm. today 5 days later Iv got terrible cramping in my lower stomach and slight cramps in my ovaries, also A slight increase in my cm. do you think I could be ovulating or would the cramps I had earlier on Saturday be when I ovulated. Iv heard of cramps after ovulation so is this likely to be that what I'm getting now. Tia 😊
