"I almost never can get appointment"

It is quite outrageous that I almost never be able to get an appointment. I am pregnant and I am trying to book an appontment with the surgery since wednesday (4 days ago). I have been told to go to a walk in centre or walk in to A&E or get an appointment from an out of ours service. However, when I was trying to book with out of ours service they could not give me appointment in advance for Monday next week which would be my ONLY day off. I am very very disapponted again and again. I am even wondering if there is any doctor working??????
