I had a stomach bug last week and a cold all this week.
From what I gather it's only an issue if you get dehydrated.
I wasn't able to eat or drink for 24hrs with the bug but babies are little parasites, they take all the good stuff. I wouldn't worry, hope you're feeling better
I had my scan today and baby was doing well - so far this pregnancy I've had 3 colds - one of which was really bad (lasted over 2 weeks and gave me a chest infection) so don't worry, baby will be fine!
