Am I late?

I think my period is due today but I'm not sure because I ovulated 2 weeks ago on a Monday AND Tuesday & today is Monday but my period didn't come so am I late or do I have to wait until tomorrow? 🤔 And im having abnormal cramping. I'm having on & off cramps about 30 mins apart. Absolutely no cramping in between then but when I do get a cramp it's like a menstrual cramp but kinda intense & it feels like it's "passing through" because I'll feel it at the top of my pelvis then makes its way to around my "bowels" & then it leaves like gas but I'm not actually passing gas but that's how the cramp passes. The cramps last for about 15 secs but the one I just had was a tad bit stronger than the one I had before that. Uh can someone please tell me what exactly is happening? 🤔
