Worried...at 6 weeks

I am 6weeks+1. Just came across a bunch of posts talking about missed miscarriages. Omgosh. Now I am trying not to stress out, because I have always read in a various of places that the chance of miscarriage goes down to 5% after 6 weeks. Someone please console me. :)

My current symptoms are: constant thirst (I drink a lot of water and i still feel thirsty), headaches, sore boobs/tender nipples, a bit of food aversion (not much), bloating, and occasional nausea...not much yet.

I know I should feel fortunate that my symptoms are all mild, I also don't want this to be a sign of something.
