mamas I need some advice..... last night I was in and out of the bathroom for an hour (sorry for the tmi) and have felt nauseous since going to bed... I am 99% sure I'm not pregnant as I had a tubal in October (I say 99% because that's how effective a tubal is lol) any ideas what I can take for the nausea since I'm breastfeeding?? I will call the Dr if necessary but I didn't want to if this is just food related lol
