Pregnancy symptoms!

Hey you guys! This is my first time posting and my first time being pregnant! I took 6 tests yesterday and they are all positive. I am 4 weeks and 5 days according to the calculator. I’ve been having terrible headaches, fatigue, and awful cramps in my stomach and even toward my pelvis and butt. Is this normal?? I’m also super nervous that I have Covid-19 (waiting for my results tomorrow). So not only am I terrified of all of the symptoms and new mom jitters, I’m also extremely worried about the baby surviving the virus. Can anyone share their experiences with normal pregnancy symptoms at this stage?? Thanks! 💕
