Dating ultrasound Mombie+2 Due December 20; TTC since Feb 2017; 2 kids; That place, Pa, United States 3069 posts

I had my first ob appointment yesterday and my dr had me schedule my dating ultrasound. Based on her computers she's saying I'm due December 17th but that's based off of a 28 day cycle which I don't have. Mine is usually 31-35. I have no idea when I ovulated, we only bd once in march, the last time was April 5th and I got my bfp on April 14th, is it even possible that I got pregnant the 5th and got my bfp that early? Anyway my main question is, if I have my scan on Wednesday and I'm only a little over 5 weeks will there even be anything to see? She's figuring I'm 5 weeks 4 days right now and I really don't think that's right.

They are all based off a 28 day cycle. They go off 14 days after the start of your period when you would usually ovulate  no matter how long your cycle is. I had 36 day cycles and still they went off 14 days after the start of my period and due date was accurate with ultrasounds early on.

All I know is I knew the exact date of O and last period with a very regular 28 day cycle. With all that being said...
my dating scans showed nothing at 4 weeks. No sac or baby only a cyst on overy. At 7 weeks I seen sac and baby.

I got a bfp at 9dpo with my daughter. I should have been 24dpo but I ovulated the day i should have been late for my period. If baby measures later they may adjust your due date.

With this last pregnancy my average cycle was 31 days and they still went by 28 days. With my other 2 children I had 25 day cycles and they also used 28 days. Due dates are just estimates regardless of ultrasound or lmp.

They will likely only see the gestational sac and probably the yolk sac at that early on

But if I'm actually 6 weeks 3 days by then would there be more? I can't remember what ds's ultrasound looked like so early on. With dd I didn't get an ultrasound until I was 20
weeks.

at 5 weeks i saw nothing but a sac ( i thought i was almost 7 weeks according to my LMP ) I ended up ovulating the day before I was supposed to start AF. Wen't back almost 2 weeks later for another scan was 6w6d. They drew HCG lvls the first visit because we didn't see anything on the screen but the sac. They were in line with 5 weeks.

It just depends. Some people see nothing that early, some people do. I realize this answer doesn't help much. 38

I had a scan at 6w exactly with dd1 and we saw fetal pole and heart beat (113bpm) but it's also very common to only see gestational sac and yolk sac

Ok thanks everyone. I'm assuming this will also be a transvaginal ultrasound right? I've never had one of those either so I'm a little nervous.

Most likely, yeah.  Nothing to be nervous about.  It's a little uncomfortable for me but my cervix is really sensitive and  every tech who's done one transvaginal scan  on me  has a habit of hitting it lol.
