Don’t go and see your GP! They don’t do routine pregnancy tests and home tests are reliable and don’t need to be double checked by a doctor.
In most areas you self refer to the midwife around 6 or 7 weeks and your first appointment will be with them.
Unless you have an existing condition there’s no need to see your doctor about being pregnant as they can’t do anything and it’s not an illness.
Anyway, looks positive to me so congrats OP
