39+3 today and past 3 or 4 days i've felt awful! I thought i felt bad previously but now i've had a constant headache for 3 days-its finally gone (thank god),no energy at all,tired by 6pm, flu like aching symptoms, feeling sick (not actually been sick),felt light headed /shakey. I cant remember feeling like this with my 1st but it was over 3.4 years ago.......is it normal?any advice so i can carry on day to day life?
