I'm just over 6 weeks pregnant. i've been ill since sunday with a cold, nausea and diarrhoea. is this because of the cold or another virus completely?

Cold and Am sickness: So although we have seen quite a lot of colds early this year, some of your nausea could be from morning sickness on top of a viral illness. Plenty of water, and I would alert your OB.

Sounds like it: But being pregnant you have to be sure you rest and hydrate. If you do not improve go see your doctor. You do not want to dehydrate
