13 week ultrasound aka first trimester screening

check it out, i'm almost done catching up on the ultrasounds! only one more post to have done by the 26th.

this 13 week ultrasound was really the first trimester screening. it was very important to hubby and i to do the first trimester screening to test for the probability of down's syndrome and other related chromosomal disorders. everyone is entitled to their own opinion on whether or not they'd terminate a pregnancy with a high risk for a disease such as down's syndrome. for us, we knew that as much as we wanted a child, any child, we weren't sure our marriage could survive a special needs child to that extent. i know we'll be patient and devoted parents, but we are also realistic and know our own strengths, weaknesses, and what we as individuals and parents can handle. that is why we opted for the first trimester screening. if we go to our 20 week appointment and find out there is something significantly wrong with the baby, we will try with all of our might to prepare ourselves for the challenges to come. but given the option to know if we're high or low risk for major illnesses at 13 weeks was again, simply important to us.

date of ultrasound: april 7, 2011

gestational age: 12 weeks, 4 days

crown to rump measurement: i wanna say she told me the baby was about 6.5cm, but i didn't get a print out with the measurement so i can't remember! the focus wasn't so much on the crown to rump measurement as the measurement of fluid behind the neck.

gestational age based on measurement: i do remember she said the baby was measuring at exactly 12 weeks, 4 days that day. still on perfect track.

due date: see, it's good they don't change your due date every time the ultrasound says the baby is measuring a little ahead or a little late. we were back to measuring exactly on that, so october 16th it is.

heart rate: i don't recall this number. again, no print out of it to jog my memory.

gender: i wanted to ask but resisted! i did, however, go home and do some research on if it's too early to tell if you're having a boy or a girl. apparently there is a theory on the "angle of the dangle". let me find the excerpt i found to send to my sister on this...

"The nub theory is basically about 'the angle of the dangle'. Between 11 and 14 weeks' gestation both genders have a penis-like protuberance between the legs. They look incredibly similar at this point, except for the angle at which they are pointing. Sometimes there are males and females at this stage which are in the 'grey area', but essentially a boy's 'dangle' is 30 degrees up relative to the backbone and a girl's is below 30 degrees.

If you get your scan at 11 weeks, it can be difficult to tell the difference between the genders. A scan at 12 weeks is around 75% accurate and at 13 weeks it's closer to 95% accurate."

i posted a photo from my 13 week ultrasound onto one of these "nub theory" message boards and 5 out of 6 people guessed girl based on the angle. i personally thought it looked to be angled upwards, but then i looked at the confirmed boy and girl photos on the message boards and it does look more like the girl anatomy. it's all a mere theory, so we'll have a better indication at the 20 week ultrasound. it's a bit too soon to buy pink based on that!

who was there: just me this time. hubby didn't need to be around to see them prick my finger for blood. he'll be at the 20 week ultrasound for sure, but he had to work this day and this one wasn't critical for him to be there.

movement: the tech said the baby was nothing short of perfect. he/she laid still when she needed to do the fluid measurements, then moved appropriately when she needed to check a few other things. no somersaults that day!

highlight of the ultrasound: being told we were low-risk for the probability of down's syndrome and a few other disorders of that nature. quite a burden lifted, honestly.

these are a couple of photos from the first trimester screening.

  1. Thank you for sharing these thoughts and for being so honest! I think this is a difficult thing to say but my husband and I were recently having this same conversation in hypothetical terms (not pregnant currently). Your belly is super cute!
