Ok so I know it SHOULDN'T hurt baby, but I'd just like reassurance.

I copped my second bout of gastro (caught from DS) for this pregnancy last week. Severe vomiting (ended up in hossie for a day on drip & zofran) and then a few days later got the runs (OMG never again pls ). Couldn't get out of bed/toilet for the better part of the week, head spins if I get up too quick and just absolutely exhausted. Am slowly on the mend now. I know (theoretically) that baby takes what it needs (and I get what's left - ha!), but I just want to be sure. Is there anything I should get checked (i.e. bug tests etc)? I think I can still feel faint movement and I have my 20wk scan soon - I just don't want to hear in 3 weeks that I should have been checked for some particular bug or other.

Also, I'm thinking best way to try & avoid in future? I'm thinking just probiotics? Any other suggestions cos I really really really don't want to get this again.

TIA

P.S. woot - second trimester!
