Cramps and pregnant????

Ok I know this has probably been asked so many times before. AF was due on Saturday the 15th. I'm usually pretty dead on schedule maybe a few days off here and there. My boobs are extremely tender which is normal before AF for me. But I've also been cramping worse than I ever have before. They're sharp pains in my uterus and last for about 15 seconds. Usually I can't even breathe during them bc they're so painful. I know light cramping while pregnant is normal. Anybody have any thoughts?? I really really don't wanna test for a few more days bc it gives me anxiety. We've been trying for 2 years now and I hate the let down. Help!!!
