Pregnancy symptoms fluctuating

Leo

Hi girls just wondering if you’s could give some insights as I’m 7 weeks 4 days and sometimes have strong pregnancy symptoms other times I’ll have none is this normal? I’m so worried like I feel normal just more hungry and sore nips but I had painful breast and sickness but they went away and I’m so paranoid😞 baby’s heart beat was 110 at 6 weeks 1 day so hopefully they stick and stay
