Am I crazy or...?

My so and I are not really trying but we’re not preventing either. I am on day 20 and I am purely assuming I ovulated roughly Friday or Saturday because of extremely creamy cm and then it was gone the next day. It was only present that day. Ever since Sunday, I have had pms like cramps. Unmistakably the cramps you get when you just KNOW you’re about to start your period. But I have a normal 28-31 day cycle, so this would be very early. I’ve never been pregnant and it’s too soon to take a test. I’m just wondering if anyone else has had cramps every day after possible ovulation. I’ve never had that much cramps before and it’s not 24/7, but it’s definitely been every day at random times. Does it sound like a random weird thing to happen or is that pointing towards a possible pregnancy? I’m 24 and he is 30, so we are both well equipped and would be happy. But we haven’t been trying every single day.
