Why is pregnancy

Sooooo difficult 😭 I’ve been feeling thee worst since week 6 and although I am beyond excited and grateful I am also very tired of being sick. One day it’s vomiting all day and nausea. The other is nausea and major headache. Then I’ll have the worst back ache and dizziness Today I have a huge headache and sore throat. Can I catch a break!!! 😭😭😭 I am so sad right now!
