Oh mama, tell your DP no way!! The longer you stay at home, the better chance you have of any hospital interventions from screwing with your labor. Great about the GBS. Stay hydrated, eat, rest, and try some nipple stim. It might take a while, though, up to an hour or more. Also, keep in mind that that 24 hour thing that OBs insist upon about ruptured membranes and infection is because HOSPITALS ARE FILTHY PLACES. Most HB midwives are okay with DAYS because the germs on your house are your own!! So stay home and get that party started!! No penetration, but orgasms are good for labor, so get lovey, too!!
Keep us posted!
