help please.🔴

So I've been off the pill for a month now and my period was due Monday. I still haven't got it yet. I've seen that if you stop your bc your period might not come? I'm two days late but for the passed few days I've been real gasy with cramps from the time I wake up in the mornings till around lunch and I've been using the bathroom a little more than normal. I'm afraid I'm to early to test because if I'm pregnant, it would of happened around March 2-4.
