Please do not book a GP appointment or attend your GP practice. If you live with other people, they should stay at home for at least 14 days, to avoid spreading the infection outside the home. After 14 days, anyone you live with who does not have symptoms can return to their normal routine. But, if anyone in your home gets symptoms, they should stay at home for 7 days from the day their symptoms start. Even if it means they're at home for longer than 14 days.
The most up-to-date public guidance is always online at https://www.nhs.uk/coronavirus. If your symptoms are serious, or get worse, NHS 111 has an online coronavirus service that can tell you if you need further medical help and advise you what to do. Only call 111 direct if you are advised to do so by the online service or you cannot go online.
