OB and Perinatologist visits

Just a quick refresher - last Monday we ended up in L&D again because I was having contractions (again). They gave me two shots of terbutaline and sent me home with procardia and instructions to follow up with my OB on Thursday. I said I would post an update if anything "exciting" came out of our OB appointment on Thursday, and then I didn't post a thing! Well. . .

The OB does an ultrasound of the girls at every visit. I have been noticing for the last several visits that there is a pretty decent size difference between Baby A and Baby B. At the scan on Thursday this was confirmed -

Baby A - AKA - Baby Olivia - 4 lbs 12 oz (up from 4 lbs 10 oz 10 days prior)
Baby B - AKA - Baby Brianna - 5 lbs 10 oz (up from 5 lbs 4 oz 10 days prior)

As you can see, not only is there a decent size difference between the two babies, baby Olivia only grew 2 oz in 10 days. She should have grown at least 6 oz (like her sister did). She fell from being in the 70th percentile down to the 41st percentile. My OB decided to refer us to the perinatologist for a second opinion.

The perinatologist got us in for a second opinion crazy fast! First thing this morning in fact. I went in with a ton of questions and expecting bad news. I knew that if baby Olivia didn't pick up on the growth that they would consider delivering me early as she may be better able to thrive outside of momma's uterus instead of in it. I was fully prepared to talk to the peri about our options. BUT. . . according to his ultrasound machine and fancy equipment the girls are measuring very close. .

Baby A - AKA - Baby Olivia - 4 lbs 11 oz (42nd percentile)
Baby B - AKA -Baby Brianna - 4 lbs 12 oz (43rd percentile)

So, Baby Brianna flipped yesterday and is now head down too (yay!) and because of this they had a bit more difficult of a time getting accurate measurements on her, BUT, they were still sure that their weights were pretty darn close. I understand that ultrasound weights can be off at this point - up to a lb off even - but my OB personally does my ultrasounds with his own two hands, and on the same ultrasound machine each time. If there was that much of a size discrepancy, he didn't make it up! I'm so confused! I mean, I'm thrilled that the girls are doing well and are so close in weights, I just don't understand how it's possible that my OB could have been THAT far off!

We go back to the OB tomorrow evening, and he will do another u/s then. I'm curious to see what he has to say about the visit with the specialist and the difference in u/s measurements because I'm just perplexed! Oh, and my OB checked me on Thursday when I was in - 50% effaced still not dilated. Woo hoo=).

Now we are taking guesses as to when these little princesses will be entering the world. . .my guess? 35w2d. . .so 9 days from now. It probably isn't right - I haven't guessed anything correctly about this pregnancy yet! Why start now? LOL! The specialist today told me he expects me to go to 38 weeks. . .this was two weeks after my OB said that he was positive I wouldn't make it to 37 weeks. Who is right??? Want to guess?? I have guesses in for October 5th (me), October 7th (Aunt Chris), October 10th (Aunt Denise and Sarah Dee), and October 14th (my mom) so far=)

Anyway, I will update again after my OB appointment tomorrow. Hope you all are doing well!
