Hi everyone, I’m looking for some honest input as I’m in a really anxious waiting period. I had a day 6 PGT-A tested embryo transferred on 13th April, so my dates are accurate. My hCG started relatively high at around 4200, but then rose more slowly than expected to about 5300 after 48 hours and then around 5700 a few days later. I had a scan at 5 weeks 2 days which showed a gestational sac in the uterus measuring approximately 5 x 3 x 4 mm, but no yolk sac or fetal pole yet, and no signs of ectopic pregnancy. The clinic have called it an early intrauterine pregnancy of uncertain viability and want to rescan. I’m due another scan today (around 24 hours later), but I understand it may still be too early to see much change. Has anyone had a similar combination of slow rising hCG and no yolk sac at this stage and gone on to have a viable pregnancy, or does this usually point towards a non-viable outcome?
