Barely any sickness (comes and goes)

5wks 6days I really haven't been sick like everyone says they are. Today and yesterday I BARELY had any symptoms or anything but days before that I was a little nauseous, like lower back pain, and little cramping below my belly... I'm just worried or maybe I'm over thinking made a Drs appt today. Hope everything is okay!! But, is anyone else like this?!?!?!?? 😖😖
