Worrying

Sk

So I had bad pain today so I went to hospital and got checked to rule out tubal pregnancy lucky enough it isn’t but ultrasound there was only a sack and they say my due date is now 22nd instead of 25th so that makes me now 6 weeks and 3 days, now my next scan is 7th of Dec but I’m freaking 😭 also it was both normal and vaginal ultrasound

Anyone else had this happen and next scan there was the baby ?
