After so many trips to the e.r and to my gyn I can say no it dose not I was sick for 14 days straight first a stomach flu and then a bad cold he may not move as much as your body a little weak but do drink a lot juice,water,Orange juice. That will keep the vitamins up :) I was on the Zpack twice so far I'm 28weeks pregnant good luck
Thanks for the comment, he's defo moving ha.. Being sick when pregnant is horrible especially sinus infections because your hole head and face are in agony plus the antibiotics make you nausas. It's mad how much they can go through and not be effected :)
