Cramping?

Has anyone ever had cramping as an early symptom? I’ve had cramps for about 4 days now, they’re mild but definitely noticeable. I’m also like extremely GASSY! ( TMI) Its over the top. I keep thinking my period is coming but it’s two days late! Took a test a couple days ago and there was a very faint line. Waiting until later this week to test again. This is our first time trying this month!
