3 test positive!

Georgie • 18, happily engaged and pregnant with baby number 1! 😍
Okay, so I've taken 3 tests, 2 different brands and coloured dye. 
Even though they were ALL POSITIVE, I still keep having this thought in the back of my mind that this is going to be some cruel joke of nature and it's not going to be real. 
Someone please give me some reassurance, don't have a doctors appointment for another 2 weeks! 😰
