Nearly 6 weeks pregnant and the worst tummy bug of my life yesterday! Never been so ill. Only managed about 1 pint of fluid yesterday and no food. Spoke to G.p who said if no better last night to have an anti-sickness jab. Sickness stopped thank god! I know i'm most likely worrying over nothing but would it have done any damage to pregnancy? 1st baby so all a bit overwhelming and had rough weekend so feeling a bit sorry for myself!
