hey we are due on the same day. I too went to u/s appt at 33 weeks and was told my cervix was short and they thought they caught a contraction on u/s machine so they were going to send me to labor and delivery. well my doc said no it is a little early but normal for body to start preparing for labor. i havent been hospitalized yet but do just told me to go home and take it easy dont do too much rest as much as possible off my feet as gravity is not your friend on your cervix.
Same thing happen to me! I was so mad i had to get an IV and I wasnt gonna meet my son. I have horrible back labor already. But I stayed off my feet. And cut down to two days of work. I feel better and he hasnt came yet 36wks ! This happen at 32wks. So good luck! Get plenty of rest.
