Advice Needed High hCG surge (7,200 at 5w1d) but ultrasound only shows a small, empty gestational sac. In limbo and terrified of a blighted ovum. Has anyone experienced this?
I am completely spiraling right now and desperately need some insight or reassurance. I am currently in ultrasound limbo and terrified that I am facing a blighted ovum, but my hCG numbers are throwing everyone off.
Here is my exact timeline:
Oct 4th/5th: Positive ovulation strip (tracking closely).
Oct 14th: Faint positive pregnancy test.
Oct 18th (approx 4w0d): Went to the ER due to weird cramping on my left side because I wanted to rule out an ectopic. HCG was 177. Ultrasound showed nothing (too early).
Oct 20th: HCG rose to 445.
Oct 23rd (approx 4w5d): HCG jumped to 2,500. Ultrasound showed a gestational sac, but the tech said it was "too small to confirm it's a pregnancy."
Oct 26th (yesterday, 5w1d): HCG surged to 7,200. Gestational sac was seen again on the pelvic ultrasound, but it still looked empty. The radiologist didn't say much, but the medical team admitted they are concerned because they aren't seeing a yolk sac or an embryo yet at this hCG level.
They have scheduled me for YET ANOTHER ultrasound tomorrow (I'll be 5w3d) in the fertility department to use their high-definition equipment.
I am so, so worried. Why is my hCG surging so beautifully into the thousands if there is no embryo or yolk sac visible yet? If it's a blighted ovum, can hCG really jump from 2,500 to 7,200 in just three days while the sac stays tiny and empty? I don't have a family history of twins and didn't use fertility treatments, so I don't think it's a heterotopic or multiple pregnancy.
Has anyone ever had numbers this high with an empty sac at 5 weeks and gone on to see a baby a few days later? Or is this a classic sign of an early loss/blighted ovum? Please be honest, the waiting is killing me.
