8 weeks and worried

Al

I just turned 8 weeks today and I just dont feel pregnant! Only symptom I still have is sore boobs ! I went in for a dating ultrasound at 7 weeks and everything was good baby had a heart rate of between 135-150 but for some reason the last couple days I don't feel pregnant! I don't have another ultrasound till October 2! Should I be worried 😩
