first time mummy😁

Hi all! Im new to this and not entirely sure how it works, however i found out last week i was pregnant.. im about 5 weeks today. However i dont have any appointments until the 28th march which is the midwife. I feel thats a bit long to wsit without seeing someone and so many things are going on in my head, im constantly worried something will go wrong? Is this normal to wait this long?
