Really worried that food poisoning has harmed baby, 11 weeks 1 day, someone put some burger cheese back in the fridge after it had been out for days and it has seriously upset my tummy. Then tonight for the first time in months vit b12 was affecting my urine turning it yellow, I’m retching nauseous. I have a history of miscarriages but not normally after heartbeat has been found. But I have found the vitamin urine thing happens when something is going wrong .
