I’m wondering how to determine how far along I am.
I had my 5 day FET on November 17/16. At my NT scan on January 26, I was given a report by my clinic and told I was 12w5d (gestational age). I am doing IPS and my Part 1 blood test was that day. I also graduated from my clinic that day.
On February 11, I went for my IPS Part 2 blood test (can be done between 15 weeks and 19 weeks). I thought I was 15 weeks on that day and figured I’d get it done so it could be analysed as soon as possible
I received a call today that my blood sample could not be processed because on Feb 11th, I was 14 weeks, 6 days. The person who took my call at the clinic seemed bothered that I needed a new requisition. She did not answer me when I told her the gestational age on my report.
This is my first pregnancy so I’ve never done this testing before. How do I determine how far along I am? Did I miscalculate?
My first OB appt isn’t until March 24.
Thanks for any replies and have a great evening! 🙂

I found this website helpful in trying to figure out calculations.
oh and congratulations!

Yeah just google it. Perinatology has a good IVF calculator.

Can’t you just ask the IVF nurse? Besides the fact that on any medical visit, it says it right on your scans or images.

Thanks for the replies, ladies. 🙂
I did ask the person who took my call at the clinic, but they pretty much ignored my question. I was a little disappointed because usually everyone has been great, but it was not my IVF nurse.
My ultrasounds only state the trimester, but not the weeks/days pregnant.
I love the ivf.ca calculator; when I was first told I was pregnant, I used that calculator which gave me the same due date and weeks/days along as my clinic. So I am not sure why there is a discrepancy now.
Hopefully I will get this figured out after my next ultrasound and first OB appt on March 24th.
Have a great day! 🙂

weightwatchers152 : did the new nurse date you based on measurements not realizing you did IVF? I consistently measure ahead and one tech mentioned a possible due date change. I had to remind them that the date of conception is not an estimate – it was done in a lab – and then they kept my dates the same.

weightwatchers152 : Sounds to me like you were dated based on measurements vs actual expected due date as determined by your transfer day. If I could guess, I would think you measured a day or two behind and that is why there is confusion. With IVF you know exact dates and that should be able to be over-ridden by your OB office.
ETA: I’m confused, is this all being done through your RE’s office? If so, then they should know that you don’t change an IVF due date based on a measurement…?

You’re 15 weeks 4 days and due date is August 5.

RunnerBride13 : Thank you! 🙂 That’s what I’ve been going by as well. The due date matches what my clinic gave me. The Perinatology calculator you suggested is a great one.
Using the gestational age given by my clinic, I assumed I was 15 weeks on Feb 11th, the day I had my blood test.
LilliV : BeverlyGeese : Thank you for your replies. I’m thinking that’s possible. Hopefully this will be sorted out by the end of this week!

Thank you ladies for the replies.
Yes, that’s exactly what happened LilliV : and
I spoke with my clinic today after our holiday weekend. It turns out that they go by fetal age, not gestational age, and I was measuring one day behind at the time I began my Part 1 Integrated Prenatal Screening.
The online calculators suggest I’m 16w+3 today, but I’m actually 16w+2.
The IVF coordinator I spoke to told me to try and go for my last blood test midway between 15 and 20 weeks, so after 17 weeks for a better result.
Hopefully all goes well or I will be doing the NIPT to avoid an amnio if I can!
Have a great day, ladies and thanks again for the helpful replies! 🙂
