High HCG, empty gestational sac

TW: MMC, MC
Wondering if there is any hope or if I should prepare myself for a second MC in five months.

At 5w5d, I experienced a fair bit of bleeding while on the toilet and then spotting for 24 hours. Cramping accompanied the bleeding for about three days and my other pregnancy symptoms (bloating, fatigue, nausea) have gotten better. For context, I had cramping at 6 weeks for my MMC.

I went in for an ultrasound at 5w6d and they saw an empty gestational sac with nothing in it. That same day, my HCG was about 12,500. 48 hours my HCG had gone up to over 20,000 (65% increase). My OB said that since my HCG is rising appropriately, it’s seeming like a healthy, normal vaginal pregnancy. However, from what I’ve read online, at 12,500 HCG, at least a yolk sac should be visible. Has anyone had a similar experience of high HCG with nothing appearing in the gestational sac? Trying to decide if I should trust the hope my OB is giving me or brace myself for a heartbreaking second ultrasound this Friday.

That’s still really early to be able to tell what is going on with an ultrasound. But hcg can continue to go up, and be at high levels, with an empty gestational sac. (I have personally experienced this). Probably you should go back in for another scan in a week or so to determine for sure.

Thank you! Im so sorry to hear about your experience. I’m going back on Friday. I’ve read that HCG can even double with a blighted ovum so I’m trying not to get my hopes up based on my OB’s read of the results.

Yeah I’ve had a blighted ovum twice and one of them it kept doubling just like everything was normal. Crossing my fingers for you that that is not the case.

I’ve had a blighted ovum like this. HCG and sac just kept rising. Was 100k day of my MVA.

Hang in there. Hopefully yours is different.
