Already worried

Amanda
I'm 4w1d and just today I started experiencing mild cramping, bloat, and gas. My first gyno appt is this Thursday but I'm already freaking out that I have an ectopic pregnancy, miscarriage, etc. Are these symptoms normal this early on?  I really need to get this worrying under control, I may be giving myself a stress ulcer! Lol
Thanks for all your help, ladies 💕
