How many weeks

Steph
I'm brand new at this and I need a good idea of when it's not 'too soon' anymore. I'm too impatient to wait for my period but I'm too scared to test too soon and be disappointed. It's only been 2 weeks since my fiancé and I have been TTC. What's the first sign you usually get and How many weeks along were you when you got your BFPs?
