I know I'm impatient, but we are excited!?!

Hello! So I am seeking advice from you mothers that have experienced what I think is the worst waiting of my life!!
My fiancé and I have been together for years, since high school, and are planned to be wed in late November of '16. 
We are both in our 20's and I have been on the pill for about a year and a half. 
We have been wanting to TTC because we think it would be very special to have our first little one here around the same time as our wedding. (I'm trying to allow myself 1-2 months recovery before our wedding which means we have been busy if you know what I mean!)
Long story short, we have been trying for about 2-3 weeks and I have taken one digital pregnancy test which stated I was negative, which I totally understand with it being so early! But I'm not sure if I'm actually not pregnant or if it is just too early! 
I obviously know I can wait until a missed period to see for sure. 
We are terribly impatient because of course, WE WANT GOOD NEWS! LOL 
Anyways, I am reaching out to hear what you ladies have to say about when you first tried conceiving and about how long it took for you to find out, how you began to notice, just various stories like that. 
I have a woman's doctors appointment tomorrow so I know I can take many questions to a professional, but I am curious of your stories!
Thanks. :-)
