I had gastro at 38 weeks with DD2. She is severly lactose intolerant but no-one knows for sure if that is what caused it, and seeing as there are plenty of healthy and happy bubs here who were subjected to Gastro in utero I think chances are pretty slim of any complications or illnesses arising from it. Just keep your fluids up and if you are worried go to the doctor.
Definitely keep up your fluids if it hits you. But drink small sips slowly, not big gulps as you will just throw it back up and end up dehydrated (I learned the hard way once).
Make sure you and your boys wash your hands frequently to help minimise the risk of you catching it too. I hope they get better soon .
