Hi, welcome
Are you able to get a blood glucose monitor? Chemists or supermarkets sell them, it’s hard to say if your sugars are very high without testing, peeing a lot is a strong indicator but could probably be a sign of others things too. You could of course call 111 for advice? Or if your very worried take yourself to A&E, you are most likely fine until Monday but I would hate to say that and you end up needing urgent care, it’s your call unfortunately and unhelpfully sorry.
