I think I’m pregnant?

I am now 4 days past when my cycle was supposed to start. I’ve tested a few times and have gotten nothing but negatives.

So not only am I late but I’ve been experiencing some horrible fatigue. Some cramping. Hunger. Increased urination. Emotional. Irritable.

Could I be pregnant? If so, when should I expect a positive test? I hear some women had to wait almost 2 weeks past when they were supposed to start their period. Just would like to know some personal experiences any momma has had.
