Anxious First Timer

I know this is a question asked a MILLION times, but I can't find an answer that fits my situation. My SO and I have decided to start TTC... kinda. We aren't actively trying as in tracking etc, but we're not preventing it if that makes sense? Well anyways... I have a kind of "gut feeling" like I had with my first pregnancy (I unfortunately miscarried) but I don't know when is too soon to test!

I'd only be about a week along, would've concieved in the middle of my fertile period. I just need to talk to someone and get an opinion because we don't want to get anyones hopes up!
