Hi everyone,
I posted here a few weeks ago because I was struggling to understand why my pregnancy was consistently measuring behind despite having very well-tracked ovulation. Unfortunately I have a difficult update, and I'm wondering if anyone has been through something similar.
Background
Previous miscarriage earlier this year, so this has been a closely monitored pregnancy.
Taking progesterone support, baby aspirin (because had very high ANA/ATAPositve results from previous miscarriage), prednisone and IV intralipid therapy as part of my protoco, aside from the usual folic acid, prenatals, omega 3, vitamin D (high dose as i'm deficient) etc.
Timeline
LMP: 26 May 2026
LH surge: 10 June (Mira LH 32.9)
Estimated ovulation: 11 June (supported by LH, BBT shift and hormone tracking)
First faint positive: 19 June (8 DPO by my tracking)
Because of all the above, I'm very confident about my ovulation date and don't think this is a case of dating being off by a week, doctor agrees.
Early hCG
22 Jun: 47, 24 Jun: 153, 27 Jun: 277, 30 Jun: 581, 7 Jul: 6,132, 21 Jul: 19,021, 23 Jul: 16,900 (declined over ~48 hours)
Ultrasounds
- 16 July Gestational sac: 12.3 mm CRL: 2.8 mm. Possible very faint flicker but no confirmed heart rate.
- 18 July: Three CRL measurements: 4.9 mm, 5.0 mm, 5.1 mm. Measured approximately 6w1dā6w2d. A definite heartbeat was seen, but they couldn't obtain a measurable heart rate on M-mode.
- 23 July (today) CRL: 6.5 mm, Measuring 6w4d So over 5 days the embryo only grew from about 5.0 mm to 6.5 mm.
My doctor also said the heart rate has slowed and appears bradycardic. She told me this does not look like a healthy pregnancy and is expecting the heartbeat to stop over the next few days.
The plan is another ultrasound on Tuesday. If and when cardiac activity has stopped, we'll proceed with a D&C on Friday. And do genetic testing on it (wasn't done previously as my last loss was at 5w).
I mean. This is pretty clear. All this, plus the cramps i've been feeling yesterday (no bleeding as i've been on 3x a day progesterone support)- this is over. I've lost my baby. Again. In the span of 4 months. 3rd overall. After every possible testing and treatment possible.
My question
I know nobody can predict what will happen, and I'm not looking for false reassurance. I mean let's be real, its pretty fucking obvious whats happening. My intuition for the last 2 weeks alone has been that something is wrong, with the measurement lag. But, I guess as one last hail mary. I'm specifically wondering whether anyone has experienced: persistent measuring behind despite known ovulation,slow interval CRL growth, a slowing/bradycardic heartbeat,and even a falling hCG...that later recovered? Or if you had a similar combination of findings, how did things progress?
I'm trying to prepare myself while also understanding whether there are any documented success stories with this specific pattern. I mean i basically know what's going on. We're just waiting for my baby's heartbeat to stop by tuesday but yeah. I can't believe i'm typing this right now. I was supposed to take my growing bump photo of 8w today. And here we are. I really thought this time it would be different.
Thank you to everyone who has supported me since my original post.
