No symptoms???

Kayla • 22! married to the love of my life! Love photography and nature.
I'm 4 weeks and 6 days pregnant with our first 
Is it normal to have no symptoms!? I only feel tired! My HCG on Monday was 269 going back again this Monday to make sure they're increasing because I had a chemical back in July. Just kind of worried I'm having nothing at all besides being sleepy all the time.
