Missing Period? Help pleaseee 😐

I was only on BC for 3 months (one cycle of the continuous pill)...I decided to stop taking it when the pills ran out...I've been off of the pill for several weeks, and my period was supposed to come yesterday. No sign of it! No symptoms at all either (I usually get cramps).
What do you think?
Has this happened to anyone?
Is pregnancy even possible at this point?
