4—weeks pregnant symptoms - Anyone else?

Anastasia

I am on my 4th week (and 3 days) and my symptoms so far are:

-Period cramps

-Fatigue

-Sleepiness

-Upset stomach (one moment I am hungry and then I feel nauseous)

Anyone else having something similar or am I the only one? None of my friends is pregnant and I haven't told anyone yet, so I have no one to share how I feel. Hope all of us have healthy pregnancies with healthy babies.
