I'm just over 12 weeks pregnant and getting sick in the evening but I'm just so tired all the time and cannot seem to function at the moment . My problem is my boss at work is so unsupportive , I never have sick days from work but I'm so tired that iI cannot concentrate at work. I told my boss and he just said pregnancy is not an illness and you need to sort yourself out and make the tiredness stop . I was appalled by this and went home sick and I now fell really stressed because of it as I have always been a good staff member . I even asked him if I could take a few days holiday but he wouldn't give me the days saying I need to give a full weeks notice . I have a doctors appointment tomorrow and I'm hoping they will sign me off . Has anyone had similar experience and will my gp sign me off?
