No Symptoms.

I am 7 weeks pregnant today and i havent had really any symptoms other than peeing alot, being super hungry and auper tired all the time. I dont get sick, my boobs dont really hurt, and im not really sure if its too early for all that or what.. i have an ultrasound on friday the 26th so im hoping everything is okay.. this is my first pregnancy so im a little uneducated about all of this
