Cramping, symptom?

Ovulation week 17th - 23rd have been having light cramps seems more cervical then uterus cramps since 23rd period due April 5th. I also had pinchy pain on my right side for about 2 days prior just randomly, Could this be my month? Or could I just be getting AF early? I don't have pre-pms symptoms I get up in am with AF and cramping usually starts in afternoon and is horrible. My breast are not tender and I have no spotting.
