Period 5 days late!!

Sharee

My period was suppose to start on Thursday but it didn’t. I started cramping Wednesday, which I normally do that the day before my cycle starts anyway. I’ve cramped everyday since Wednesday but still no period! My cycle is always on time like clockwork. I’m not pregnant because my boyfriend and I always use protection. And I haven’t been stressed about anything. What could it be?? Why did I not have a cycle for this month?? 😩
