early scan.. ?? Scared

Jess
Just had a phone call from the nurse I saw yesterday, she said my blood confirmed I'm pregnant but I need to go to see the early pregnancy team in Hospital for a scan because of the pains I have been having.. I haven't had any bleeding at all but I'm so scared .. Anyone else had an early scan..nurse has told me I'm 5w2d but others have told me I'm 7w1d
