So confused!

Cathi
Hi - my first time posting. My period is 2 days late (after a year of trying) so I did a test and got this.. I thought it was definitely positive. However, currently on holiday on a cruise and so went to see the ship doc. He did a urine test and said it was negative! He said my test might have just been an evap thingy. As I'm on a cruise i have no other tests with me, and there are none to buy, so I don't know what to think any more! Any thoughts?!
