Question About Early U/S

**Warning:  DC mentioned**

Hello, 

I used to be on the IF board, and then the IF Vets board, a long time ago under the name patchen30.  I was very active and had thousands of posts, but I have not been on in a couple of years.  I forgot all my log in info and the email address I originally opened my profile with is no longer valid so I'm starting from scratch.  I do not remember exactly the etiquette but please know that I am trying to be sensitive and hope that I don't upset anyone.  I have a couple of questions and I know you all to be experts.  My history is as follows.  

TTC beginning in 2008

4 rounds of IUI in 2009 (all BFN)

3 IVFs in 2010, one w/ a m/c, the rest BFN

1 FET in 2011 that resulted in DS

1 spontaneous pregnancy in 2012 that resulted in another DS

I am currently pregnant with another spontaneous pregnancy and I'm very nervous.  The first day of my LMP was sometime around Aug 14-16.  I got a + OPK (or maybe it was ALMOST +, I'm not sure as I didn't test the next day) on Fri Aug 28.  We BD on Aug 29.  I got a BFP on Sept 14.  I went in for b/w on Sept 17 and as they had nothing to base it on all I got was a call that I was pg, and they told me to come back Mon Sept 28.  The call I got that day was that my numbers "looked great and were rising beautifully".  I didn't ask for any info about my numbers b/c I know I would Google and overanalyze.  I assumed I ovulated on Aug 29 or 30 based on the OPK.  I went in for an u/s today, which would make me 5w5d or 5w4d.  The RE said it was "exactly what he'd expect to see for 5 weeks"...when I told him I thought I was a bit more than that he just kind of shrugged his shoulders.  He told me to come back in a week and a half for another u/s.  I don't know how big the gestational sac was and I don't know whether he saw a yolk sac.  

My questions are:  a) if he saw a yolk sac, would I be able to see it on the u/s?  I just saw what looked to be an empty sac.  b) if he didn't see a yolk sac yet, would that be worrisome at 5+ weeks?  c) if I had a + OPK on the 28th, BD on the 29th, would the 29th necessarily be the date we'd be counting forward from, or could fertilization have taken place on the 30th or 31st?  I know much more about IVF where you know exactly when to count from b/c fertilization takes place on retrieval day.    

I know I don't have a lot of info but I'm terrified to ask too many questions b/c I've been down that road before of information overload and I end up becoming obsessed and scaring the h*ll out of myself.  I did it for 3+ years while trying to get pg w/ DS #1.  

How does this sound to all of you?  I'm just in that limbo, petrified stage...

Correction - I went back for b/w a second time on Mon Sept 21st.

I'm not sure how to answer your questions except to say can you call your RE and ask him exactly what he saw? If it's worrying you this much that's what I would do. Also your first day of LMP is a span of a few days and since you didn't do treatment to get pregnant that's what you have to go by in order to figure out your date until they can do dating u/s.

Mid 5 weeks sounds about right if the first day of your LMP could have been Aug 14-16 and think the relevant BD was Aug 29th. My LMP was August 13th and I had an IUI on August 26th. I think with natural pregnancy your fertilization could have been up to several days later especially if you aren't 100% sure on the day of your positive OPK. I think calling your doctor and asking for reassurance is the best thing to do but everything you are saying sounds reasonable.

Since the doc said that what he saw was right on for 5 weeks, I'd say that's good. I'm pregnant from IVF so I pretty much know that today I am 10weeks, but according to the u/s I am a few days past that. I just think your u/s was too early to be very exact. I'm sure all of your calculations are right on, but I'd wait for the next u/s (which would be more definitive) when I suspect they can do the gestational dating. It's easy to say don't worry, but I know how it is. Just try to be patient. Hope it all goes well.
