So I'm 35w5d pregnant with 1st baby and last night I started feeling really nauseous, it was like morning sickness all over again! Have been vomiting all day, every 40 minutes or so and also have a bit of diarrhoea...feel really run down and crappy now, not sure if it's a stomach bug or a I ate something undercooked or I've read of a few women getting like this a day or so before labour begins... are stomach bugs dangerous during pregnancy? Haven't eaten in like 24h because I can't keep anything down..sipping on water ok though...will I hurt my baby by vomiting so much?...
