TMI ALERT! FTM NEEDING ADVICE!!!!!

Hi, First time Mom. Finally pregnant. Got my positives on August 20th and 21st. Estimating I'm around 4-5 weeks along. My first appt is Sept 17th, 2020.

I've been mildly cramping today and had this a few times. Is this normal? I'm so scared because I'm so excited and want this baby to stick!!!!

Nausea still this morning

Boobs still hurt

Not as hungry today

Tummy stretching feeling

Back kind of hurts

It just feels like my period is coming but then all day it was light like this. What gives??? Should I call back and ask for an earlier appt????
