true CPD?  

post #1 of 4

What are the signs of true CPD?

I understand that CPD can't truely be determined until labor. I'm still concerned, though. Is it just a matter of mom going into labor and pushing and pushing and pushing and baby never engages, much less comes out?

I'm concerned about my upcoming birth.

My DD (first pregnancy) was born via cesarean for suspected CPD. I went to 42 weeks with her without a single contraction, no dilation, no effacement, and a posterior cervix. She was also floating really high and didn't even starting to engage. Bishop score of 0.

My doc also did pelvimetry (which I do understand to be largely worthless) and determined I have a narrow android pelvis. I was given the option of an induction but because of my low Bishop score, was told that it would likely be unsuccessful anyway. So I opted for a scheduled C-section, 2 days later. I gave birth to a healthy 6.5 lb baby girl.

So this time around, I desperately wanted a VBAC and I felt at home was the best place to accomplish that. I felt pressured by my previous OB to have the section and I wanted to avoid it this time. I felt that if I took matters into my own hands, I'd be much more successful at a vaginal delivery. I have a lovely MW who also has faith that I can birth vaginally. So I've got plenty of support on my side.

But now that I'm 38 weeks, I've feeling panicky that DDs birth is going to replay itself. Still no contractions...not even a single BH the entire pregnancy. Baby very high still. I know that subsequent babies don't often engage until labor, but it still kinda feels like this is should be more like my first birth. I don't know if I'm dilated or anything because we haven't done any internal exams. I just know that without any contractions and with a very high baby, things seem exactly like they did before.

It also doesn't help that my mom never delivered vaginally either. I was an emergency cesarean because of a placental abruption (something completely unrelated to CPD). My younger brother (only sibling) required a section because after my mom had been fully dilated and pushing for hours, he never engaged. Doc volunteered to give her as much time as she wanted because he was tolerating labor well, but did say that it seems unlikely he'd engage later, if he hadn't already. Is this true CPD?

I'm just really scared. I know CPD is rare and a lot of women get labeled with it unnecessarily. But what about women where it is a true diagnosis? I've been trying to do some research on true CPD but all I keep coming across is that if you've never had rickets or a broken pelvis, you're good to go. But is there any healthy woman, no matter how rare, who just can't seem to birth vaginally? (I'm not assuming that I'm one of them, btw)

And what about the not going into labor on my own? I realize 42 weeks is somewhat arbitrary, but my midwife has to follow it to maintain her license. Since it's risky to have a medically induced VBAC, what are my options if natural remedies don't work? Another section?

Hi Mom-

I'm not a BP, and I have NO answers or insight to offer you, but I just wanted to offer you support and good wishes. It sounds like you are going through a stressful time and are asking lots of good questions. I hope you find the information and reassurance you're looking for.

Hang in there!

I don't have time to answer all of your questions, but wanted to address your concern about your baby not being engaged with your current pregnancy.

The entire shape of your uterus (specifically your lower uterine segment) is different once you have had a baby, regardless of the route of birth (vaginal or cesarean). So, since this is your 2nd baby, your baby won't engage until either just before labor, or during early labor....it is really perfectly fine.

Also, MANY women never feel BH contx.....you are having them, absolutely. You began having them early in your 1st trimester.

Your body has grown your baby, and that is amazing in itself. Your body will know just what to do to birth your baby, as well. Our uteri are incredible!

(BTW, I've known many women diagnosed with 'narrow android pelvis' to go on to birth vaginally with no problems.

I had a mom who was told in her first pregnancy that she'd need a c-section from 36 weeks on b/c of her baby's failure to engage. She labored for days and ended up with a c-section "because her baby wasn't descending" when she pushed (twice ).

She had a successful VBAC this year with a bigger baby.

I have seen three true cases of CPD (lots of labor, lots of position changes, and in a couple of cases lots of pushing, but no vaginal birth b/c babies just didn't fit). Even in those cases, I would never dream of telling the mom that she can't VBAC. Sometimes one baby just doesn't fit as well as another might.

Be sure to talk to your midwife about these concerns. She'll need to know that you have them in order to help you through your labor (because you WILL labor this time!! ).
