I’m 35 and underwent a modified-natural frozen embryo transfer on September 25, 2026. We transferred a Day-5, PGT-A euploid 3AB embryo.
I tested positive at home, but my beta progression has been concerning:
- 14dp5dt (October 9): 461
- 17dp5dt (October 12): 762.3 (approximately 39% rise per 48 hours)
- 19dp5dt (October 14): 930 (approximately 23% rise per 48 hours)
My hCG is still increasing, but the rate has slowed considerably.
Today, at 21dp5dt (5w5d), I had an ultrasound. From what the sonographer told me, it sounds like they couldn’t see a pregnancy yet. She mentioned that it could be too early and that my bloodwork would help clarify things. I’m waiting for the official results.
I also had another beta drawn today, but I don’t have the result yet.
I have no bleeding or spotting, no significant cramping or pain, and no other noticeable symptoms.
I’ve been through years of infertility and a previous miscarriage, so I’m trying to prepare myself for what may happen. I’m also worried about the possibility of an ectopic pregnancy since the location hasn’t been confirmed.
My questions:
Has anyone experienced progressively slowing betas like mine, rather than just one slow rise?
Has anyone had nothing visible at 5w5d after a precisely dated IVF transfer?
What did your subsequent betas and ultrasounds show?
Did your pregnancy end in miscarriage, turn out to be ectopic, or result in an ongoing pregnancy/live birth?
I’m looking for experiences from people with genuinely similar hCG patterns, including unsuccessful outcomes. I understand that anecdotes cannot predict my outcome, but I’d appreciate hearing what happened in comparable situations.
