Pregnancy Symptom help?

MissK
I have a doc apt Oct 20 and will find out for sure how far along I am, but according to Glow i am 5 wks 3 days. Is it normal for me to be nauseous only sometimes? Like not everyday? I'm just afraid of something being wrong.  Other then that I'm just sleepy and my boobs are sore.  I'm just so afraid of something not being the way it should.  We have tried for so long, and it finally happened.  I want everything to be okay!
