I am 30 weeks pregnant. Yesterday I asked my niece to pass me my glass of water. Her mum told her to wash her hands first as they had just been walking a friends dog. She however, just picked up the glass (with her fingers on the edge) and passed it to me. I stupidly took a sip then thought better of it and threw it away. I don’t know whether she had been picking up dog poo or just touching the dog or what but I am so worried now that I may have caught some bacteria or something that could harm my baby. Should I be worried?
