2 days late

Andrea
My period was due 12/29, I tested 12/27 negative. So at that point I was over it and was figuring this wasn't our month. Well, 12/29 came around... aunt flo hadn't shown up yet. Took another test. Negative. Now we're on 12/31 officially 2 days late, and still nothing. Ever since ive stopped my pill, ive may e been 1 day late, but have always started on the day i was late. I'm really trying to not get my hopes up.. because both test said negative. Some people told me it could be too early to show up on the test. Ideas? Opinions?
