Should I test?

So my period is 11 days late and I'm worried I could be pregnant. I'm on the pill and we don't use condoms. I've been feeling pretty tired and crampy, but that could just mean my period is going to start soon? My boyfriend says I should just wait, and if I don't get my next period when it's scheduled then I should start to worry. My periods are pretty regular because of bc but sometimes they vary? Any advice to soothe my worried brain? Haha
