Symptoms coming and going?

i’m 4+5 and my symptoms seem to have eased off. I’m still crampy now and again but less so. Still gassy and bloated.. and (sooo) hungry. But sometimes i don’t feel pregnant at all.

But is it normal for symptoms to come and go? The feeling of worrying constantly is difficult and my first appointment isn’t until i’m 9-10 weeks.

Any advice to keep calm and positive appreciated x
