Do you always get menstrual cramps?

I ask because I haven't had them for the last 3.5 years while on the pill (yay pill!), but they haven't returned this month now that I'm off the pill and actively TTC.
I'm pretty sure I used to get them every single month, but I haven't had them yet this month, and I'm on the 3rd day of my early period. I actually thought it was just IB the first two days since it was early and I had no cramps. Or maybe it's because this is the first month off the pill? Maybe I should just be grateful there's no cramps this month and move on lol.
