spotting, cramps, negative test

I don't usually post on here but I need some peace of mind. I'm 24 days late according to glow. I've been spotting on and off for about a week, give or take. I took 2 pregnancy tests, both negative. I really don't want to be pregnant but I'm beginning to think that I might be. Any suggestions or thoughts? Kind of afraid to see a doctor because I'm afraid of what I might find out.
