I am 8 weeks pregnant and have been suffering from non-stop sickness and tiredness. I also have an under active thyroid which makes me very tired as well. I am a primary school teacher and have had to take a couple of days of work. I am really worried that I am not going to be able to cope with being at school because it is such a physically and mentally demanding job - I am on my feet all day. Does anyone have any advice for how I can cope with all of this? Thank you in advance from a ridiculously emotional mum to be.
