By the way, most moms to be get diarrhea before labor. I think it is mother nature's way of clearing us out a bit before the big event. Vomiting, not many women have this in labor. I did but in reaction to painful contractions-- part of my pain response. BIG FUN. LOL
Could you also have eaten anything bad?
Super important to keep hydrated. Take small sips of liquid as big gulps or large amounts may make you vomit more. I was severely dehydrated by the time I go to the hospital. Made things more complicated (had 6 bags of fluid and my heart rate was skyrocketing). So, stay hydrated.
Call your doctor if unsure of what to do.
good luck
Well, yes. You can be. Have you started to time the cramping?
