I'm 31 weeks (today) with twins and I've been feeling really rough today, but I thought it was just 3rd tri tiredness plus recovery from a tough last few weeks at work.This afternoon I tried to go out to meet a friend and almost fainted. Came back home, went to bed and decided just now to take my temperature just to be on the safe side and found out it's 39! So its might explain why I'm not feeling well, but I'm wondering if I need to be worried? Is it high enough to be a problem - should I call someone? Advice from anyone more experienced would be so welcome!!
