Ok Spanish Inquisition this is a tough talk, but you are measuring very small. As of 20w2d you are measuring 18w5d. We went in for an ultrasound last Monday, and they said you were in the two percentile which is very scary. Like super scary. Enough that we have to go in for more measuring next week and to see a genetic counselor. So, hear me out, I think your due date is wrong. Kate knows the last day of her period but there’s a lot of debate about the day you were conceived. The thing is we weren’t expected you hence the name, so we weren’t tracking very closely since… ya know we were diagnosed as infertile (hooray…) So Kate doesn’t actually know when she was ovulating but I’m like 90% certain our conception date doesn’t line up with the due date you get when you have a 28 day cycle.
Part of my failed belief is “doing it” has become rarer thanks adulthood and having children, so I’m pretty confident we only did it once and it happened on March 25th, but if you look at our due date we most likely conceived you on March 19th. Ok hear me out this is where I start sounding like a crazy person… we got a new bed on March 17th, and I was very convinced we needed to do it to break it in… but we didn’t (as far as I can remember, your mom was pissed at me on the 18th) and I was like we really need to do the deed (I am so sorry I am basically writing a math post about having sex) So the next logical time would have been the following weekend. Then your mom tested positive 11 days later which is like what we had with your brother. So, if you factor that as our conception date, when your mom tested positive, plus the fact you measured a week behind at your first appointment makes me think there’s a good chance you’re a bit small but not THAT small. Aka you’re 3d behind not 10d and that is a HUGE difference.
Of course when your mom had the initial appointment the doctor was like eh we don’t need to change the due date because second babies often arrive early and that will probably line up with this incorrectly written down due date, but if she’s deliberately putting in the wrong due date but our ultrasound is actively measuring against the wrong due date as correct, maybe you are just fine and all our assumptions are just wrong?
So here I am like a crazy person because I guess the alternative is there’s something really wrong and you aren’t getting the nutrition you need, so you aren’t developing properly, and I spiral and spiral and spiral. No one wants that. Of course, Kate is annoyed by my deep dive dating, and I am really kicking myself for not writing any exact dates down when we found out you were coming. Like if you had asked me when we found out Kate was pregnant, I would have been 100% sure the day you were conceived /sigh. Anyway, I hope you’re ok 🙁
