Flippin' heck! No wonder you told us to look here and didn't say anything on FB
I've not experienced anything like that but why not leave another few days and try another digital one and see what happens. At worst, can you get one done at your docs? I know in the UK they take about a week to give you a result but at least you'd know for sure if the shop bought ones are giving you odd readings.
Also, are you doing the test first thing in the morning when the old preggers hormones are highest?
Have a look at this link hun and see if any of these things apply to how you did the test:

Keep us posted (best to email me on FB as I'm rarely on here now).
