5 days late, but negative tests

30 years old, husband and I have been ttc for a year without even a hint of success, going to Dr about it next month. I've always been very predictable with my periods, never more than a day late. Never in my life had a pregnancy scare, or missed period, nothing like that.

All of a sudden this month I'm 5 days late. Taken multiple tests, 4 different brands, all have been very distinct negatives.

I'm just very conflicted. I've gotten my hopes up previously and they crashed down very hard, so I've gotten to a point of refusing to let myself hope.
