How common at false positives/evaporation lines?

[RedWineAndCheese]

I am at flaming centreparcs and I don't think the shop sells pregnancy tests...!

I did one test yesterday and one this morning. One of them (not sure which) is a positive, but if it was yesterday's test than it's way after the 10 minute window. And why would that be positive but this morning's negative? Although I am testing early...

How common are evaporation lines? False positives?

And where to buy another test?? I don't think I can wait until we go home, and I am with friends who cannot know anything about this yet! Hence the hiding of tests in carrier bags in my luggage...

A result out of the time window should be ignored. Id wait and see if you get your period on time and forget about testing on holiday.

Thank you kat

I know waiting is the sensible thing to do. It's just my own impatience ;-)
