Hey ladies so I went into the er today cause I thought I was in labor I'm 40 weeks and 1 day they told me the baby is still very high I'm 3/4 cm dilated and 50% effaced but Drs worried I'm going to have to have a c section be she's not down where she needs to be she told me to look up some exercises that could help her get down where she needs to be but I have an ultrasound Friday to see what's going on and if she's not down where she needs to be it's looking like I'll have a c section my ? Is is how many of you have been thru this and what was the outcome plz help I'm terrified
