Gestational Sac Size

Okay I am being a bit of a paranoid android and just need some people to say everything is gonna be fine hahahahaha!
Anyway, went to OB yesterday and he did a transvan scan and measured the gestational sac and it was only mean size of 9mm (width 6, length 12), which according to him would mean was about (I think he said) 4 weeks and 6 days whereas I am thinking I am 5 weeks 4 days (yest). When I google information on it, the results seem to say you sometimes don't even see a gestational sac til 5 weeks and the dating is calcualted on the following:

Gestational Sac: Gestational age = 4 weeks plus (mean sac diameter in mm x days). This relies on the growth of the normal gestational sac of 1 mm per day after the 4th week of gestation. For example, a gestational sac measuring 11 mm would be approximately 5 weeks and 4 days gestational age. (4 weeks plus 11 days = 5 weeks and 4 days).

Soooooo, then when I left he said to go back next week for another scan to check size and see if there was a heartbeat. There was a yolk visible in the sac so that is a good sign. But as I was walking out the door he patted me on the shoulder and said 'of course, it could be an early missed miscarriage' which of course now has me freaking out.

So, from what that information says about, I would have thought the sac was about the right size, maybe a couple of days out but gee....I just want everyone else to read it and say don't stress too much hahahahahaha!

Sorry about the novel, I will just be SO MAD if anything goes wrong!! haha!

What a dick for saying that it could be a missed m/c! Grrr sometimes comments like that are better left to ones self as even if it *was* (and I bet it's not), how is this knowledge gonna benefit you right now??

Anyway, at this early stage just seeing a sac is great and all you can expect to see. I had a scan pretty much the same time as you and another about 7 weeks...then we could see the heartbeat clearly!

Measuremens can be out at this stage too I think, and even though DP and I were charting so KNEW when we BD etc...ours was still out a few days until later in the first trimester when it became a lttle clearer...but we were still out. Apparently (we shall see in a week or so who was 'right' lol)

Good luck , am sure it will be fine. But stop Googling. Goolgle is NOT your friend during those first 12 weeks...(trust me.... )

No have not had any HCG done..they don't seem to do it over here. I am just not going to stress about it coz it doesn't help and see what happens on Thursday-hopefully we see a lovely little heart beating!!!

I really also think it depends on the actual machine they use and how old they are. For instance with McKayla in SA I saw so much more each time. She had a heartbeat before 6 weeks already. On some machines you only get to see it closer to 10 weeks.

I had a scan with this one before 5 weeks and they could just see a gestational sac without a definately tadpole and also got the comment about it is too early to determine if it is a viable pregnancy nonsense. Two weeks later and my due dates actually changed again. So I really wouldnt worry too much (easier said than done) until you go in next time again.

Your DF is a wise man It is entirely possible to be a few days out, because the date of ovulation doesn't necessarily mean the date of fertilisation, if you know what I mean. I KNOW when I ov'd for these two, and when we BD (as we only BDed on one possible day) but at the first scan at 7w I was still measuring out (behind) by a couple of days.

Hopefully at your next scan you should see something a little more promising - I know at our scan place they like to wait until 7w to look for a heartbeat as it's far more likely that one will be seen and therefore prevents the stress like you're going through....

Good luck!!! And grrrrrr at your doc for his stupid comment!!

Nat a couple of my pregnancies I was told similar things re: looks small and basically wait and see if it progresses or if Id had an early mc... both times baby continued to grow - all was ok!! I think it's pretty standard for Doctors to warn that it is possible in the early stages when dates aren't measuring up.... I guess there are people out there that would need to be told as they aren't as educated on the matter IYGWIM... But yeah it fully makes ya stress when more than likely you need not!!! all the best for Thursday
