Period 4 days late & negative prego test??

I've taken two prego tests, one the day before AF and one on day two of missed period, both negative. 🙁 Still no sign of AF and I'm on day 4 now. I will be taking another test one week after AF was supposed to come to see if the test is positive. I've had slight bloating and a small amount of cramping for the last week (not even bad enough to put heat or anything on). I took two pregnancy test, both show "not pregnant". Anyone else been in this boat and ended up being prego?!
