Dating u/s for VBAC?

Do you think a dating u/s for VBAC might come to bite me in the butt later? DS was born at 40w6d and I was hoping to get a couple extra days before the "due date" pressure began and I hope the u/s doesn't show the baby is bigger than EDD at this point.
On that note, did your midwife/OB discuss how far past your due date they would "allow" you to go? I know it's ultimately my decision, I'm just curious if anybody has been given some sort of timeline. What is the real concern about going past EDD w. VBAC medically speaking?
DS born via c/s 11/08 and med-free GD VBAC DD 3/11!

Re: Dating u/s for VBAC?
I had an u/s date my pregnancy. ?It just happened that way because I didn't have a cycle before the pregnancy and didn't even know we were pregnant until the ultrasound looking for something else. ?
My OB also gave me a timeline and they wouldn't let me go past my due date. That was the main reason I switched to a midwife and did a homebirth. ?My MW did not give me a timeline and would let me go I think she said 42 weeks as long as everything looked ok with the baby. ?I didn't need it since I had him at 39 weeks.
I'm with a midwife again, but a hospital birth. With DS they said they'd let me go to 42 weeks, but as we were discussing things she said she wanted to do the u/s b/c with VBAC they don't allow you to go very far past your EDD, so I definitely need to get clarification on what they consider that to be!
I'll be honest and say that I know DH is totally against home birth and I don't want the added stress of non-supporters. Did you find that to be a problem? Plus I really did like the hospital where I gave birth to DS and it's only 7 min. away. DS was in a bad position and I honestly think he may never have descended on his own, although it took me a long time to come to terms with that. So I'm hoping the due date thing won't even be an issue, but ugh!
They are going to assign you a due date either way, and a dating U/S this early is very accurate. If anything, it will push your due date later than using the date of your last period, which is what they would use otherwise.
Do you know when you concieved? I also never had a period before I got pg again, but I knew within a week when I concieved, so I consented to the dating u/s. I was dated a week later than the latest I knew I could be, which I thought was great - until I had my 20 week u/s, and they dated me two weeks earlier! I talked to my midwife, and she agreed to push my due date back a week (which is about the latest I estimated I'll be 40 weeks). So I dunno, 9 weeks is a good time for a dating u/s if you're going to have one, but it's something you'll have to really decide for yourself - I wouldn't have done a dating u/s if I had been charting or anything.
As for going past 40 weeks - I've had mutiple midwives tell me there is NO evidence or studies showing increased risk of uterine rupture for a VBAC to go past 41 weeks. Be really careful about your provider - there's a decent amount of providers who say they're supportive of VBAC, but then add the caveat that you're only "allowed" to go to 40 weeks. I'm pretty sure my hospital does repeat c-sections at 41 weeks, but I'm preparing myself to refuse it until I officially hit 42 weeks 1 day (let's hope it doesn't get that far, though!).
Are you a member of your local ICAN mailing list? They usually have good info about how VBAC-friendly your hospital and provider may actually be. This link from ICAN lists hospitals that allow, ban or have de facto bans (they officially allow VBACs, but no doctor will do them) for VBAC right now...https://www.ican-online.org/vbac-ban-info
Good luck!

See, I'm thinking I'll lose a couple days (well add I guess) b/c I told them my LMP was 3 days after it actually was to buy myself extra time in the end. The midwife gave me an EDD of March 11th even though based on my real LMP and O date I'm closer to March 8th, that would have been ideal for me.
I didn't know at which point the early u/s are not as accurate anymore since I'll be closer to 10w at that point? I definitely wouldn't have cared as much if I weren't going for a VBAC, you know?
Ah, I see. In that case, I'd turn down a dating u/s then, I think. But they are usually the most accurate around 9/10 weeks, so I wouldn't worry about that part.

I only did the dating u/s at 9w0d because I thought that it would buy me more time, and it did! 3 extra days!
In your case, it seems that you think that it wouldn't get you extra time, so I'd be leery of doing it. (Not so sure about VBAC info, but it sounds like a lot of other women here have some great advice!)
Yeah, I live in the city - I haven't made it to a meeting, but the message board is really helpful, especially if you have questions about specific hosptials and providers.

It sounds like you don't trust your midwife, since you lied to her about your LMP. Maybe you should look for someone you trust more? Also consider that 3 days could mean the difference between your baby being considered premature/preterm or full-term. Pre-term might mean your baby has to spend time in the NICU for observation after birth, and in most cases it disqualifies you for home birth or a birth center. What you really should be looking for is a care provider that you trust enough to be honest with, and an accurate, early ultrasound. 1st trimester fetuses rarely measure bigger than they should on ultrasound.
