IVF (FET) - Due date changed due to the baby's measurements

Hi mama, first of all congratulations on your successful FET and please know your anxiety is completely valid and understood by so many of us here. A few things that might help ease your mind a little: Dating by embryo transfer date and dating by early scan measurements don't always match up perfectly, especially at this very early stage. At 5 weeks, even a tiny difference of a few days in how the embryo implanted and started growing can shift the measurements by a week. A 2mm embryo with a visible heartbeat is actually a really positive sign at 5 weeks. The heartbeat is the most important thing right now. That is what matters most at this stage and you have that. Gynaes can sometimes come across as cautious or neutral in their language during these early scans and it can feel discouraging even when there isn't necessarily cause for alarm. The fact that he scheduled a follow-up scan in 3 weeks rather than sooner suggests he isn't in panic mode, he just wants to monitor growth as he should. Three weeks feels like forever to wait, I know. But that window actually gives the baby meaningful time to grow so the next scan will show much clearer development and give you and your gynae a much better picture. You've come so far to get here. Hold onto that heartbeat. It's doing its job. 🤍

I totally understand the anxiety, especially when the dates don't match what you expected. The thing is, with FET the embryo age can differ slightly from transfer date depending on when it was created, so a one-week difference isn't unusual and doesn't necessarily mean anything is wrong. The fact that there's a heartbeat is actually a really good sign at this stage. I'd say try to stay calm until your next scan in three weeks, though I know that's easier said than done, and if you're still worried in the meantime, you can always call your gynae's clinic to ask a few clarifying questions just to put your mind at ease a bit.
