I'm 19 weeks along and struggling to do anything at all - feel constantly dizzy, sick and now have a sore throat. I'm drinking litres! I'm just so hot and can't cool down - last time I felt like this was 2 years ago when 36 weeks pregnant!! My bump feels huge!! Should I bother my GP with it or is it just old age and decrepitness catching up with me!? (I'm 35 so not ancient but certainly feeling it!) Anyone else in their supposedly 'cheery' second trimester and feeling like absolute rubbish?! Heat, age, or actual illness?!
