Advice??!

So I am on sprintec and last month my prescription kept getting messed up so I did not have it for about a month. This month I finally got it and I haven't gotten my period yet. I am more and two weeks late. Before I ever started BC my period were always off. During the month of not having the pill, my boyfriend and I did have unprotected sex multiple times but he pulled out with plenty of time before he came. I am having period like cramps and am irritable and am having other period signs but no period.

Does anyone have any idea what's going on? Or

What should I do?
