6w2d scan with Gestational Sac but unconfirmed Yolk Sac (fuzzy shadow). Is there still hope?
Hi everyone,
My wife (41) and I are in agonizing limbo after our scan today and could really use some honest feedback, similar stories, or insight into our ultrasound image.
Our Context:
- This is our 8th IVF round overall. We yielded 3 euploid (PGT-A normal) embryos.
- Our first 2 euploid transfers failed to implant entirely.
- Before this 3rd transfer, we did a massive protocol shift: fixed a hydrosalpinx, treated her endometriosis, and moved forward with a True Natural FET using our final embryo (a Day 6 euploid).
- For the first time ever, we cleared implantation!
Our Beta/HCG History:
- 9dp5dt (Day 11 baseline): 1,186
- 11dp5dt (48 hours later): ~2,000
- 5w3d: 7,513
Her progesterone dosage was ramped up between weeks 5 & 6 Despite this maximum rev-up, her progesterone levels have stalled and remained flat at 81. Our doctor is a bit concerned—he wants her progesterone above 100, and feels 81 is too low despite the maxed-out support.
Ultrasound History:
- First Scan (5w2d): Gestational sac measured 8mm. Completely empty, no yolk sac seen yet.
- Second Scan (Today, 6w2d based on measurement, 6w3d calendar math): Gestational sac has grown on track to 15.3mm
- However, the yolk sac is still not clearly defined.
The doctor was very cautious and honestly sounded a bit pessimistic. He noted it is not completely blank inside, but shows a slightly fuzzy inside which he called borderline. It seemed like he's not yet convinced it's going to progress.
Our Questions:
- At a 15.3mm sac size, how probable is it for the yolk sac to clearly show up over the next few days? Have any of you had a "blurry shadow" turn into a viable embryo a week later? if it was a blighted ovum would it be completely blank?
- Has anyone had success with a progesterone level stalling in the 80s despite being on maximum supplementary doses? Did your clinic demand it be over 100?
We are staying strictly on our medication protocol, but our hearts are completely guarded. Thank you so much for reading.
