Not feeling a thing..

Manda • 22 years old. Happily married. FTM!! Very excited!!
Ok so since I found out that I was pregnant my stomach was having stomach "spasms", my nausea was unbearable, and I couldn't sleep for the life of me. Went to bed at 2am last night, woke up this morning with no stomach "spasms" at all through the day, my nausea hasn't been as bad I can eat and I've been sleeping all day. My breast are super sore, mood swings are horrible, and I having slight pain in my left side. I'm 4 weeks and 4 days. Is it normal to feel "normal" this early?
