Is this normal? 🤢

Hi all, I am 6 weeks and 2 days pregnant. On Thursday ( 5 days ago) I started feeling nauseous and my stomachs was doing flips. I’ve had a bit of diarrhoea but mainly just weak/ nauseous. Today I was feeling so much better. Woke up feeling great, then come the afternoon. Worst I’ve felt out of the five days and ran to the bathroom- bad diarrhoea and vomiting! Then very bad cramp in my stomach think from the vomiting. Is this normal? Just laying down atm and no cramps anymore but back to just nauseous and tummy doing flips again! Feels more like a stomach bug than morning sickness I don’t know if best to get in touch with my doctor or not about this?
