How likely is miscarriage after heartbeat? Embryo is euploid (PGTA)

[c1234h]

Hi! Currently pregnant after frozen embryo transfer. Embryo was genetically tested & is euploid. Scan over the weekend showed heartbeat at 5w6d so super early.

Just wondering how likely a miscarriage is now, having heard hb? Have had several chemicals & an ectopic so familiar to losses but also have DD from past FET who was also euploid. Praying for a repeat & that meds will get us through 🙏🏻🤍

Hello - I also had a FET and was extremely anxious - am now 15 weeks. I found this website very reassuring and would check it every day: Miscarriage Odds Reassurer (datayze.com)
5w6d is a super early heartbeat so I would personally be reassured by that. I know how difficult it is, all I can say is keep going day by day and it will get easier, but I know it feels like a long dark tunnel of anxiety.
I read somewhere that heartbeat at 8 weeks means very high chances it will successfully continue, so if you want further reassurance get another scan in a couple of weeks.
You've got this!

So the heartbeat being a good sign is factored in to that link that @graygoose posted - essentially every week in pregnancy the chances of miscarriage decrease. I'm not someone with a positive experience unfortunately, but statistically you're far less likely to have a miscarriage than a healthy pregnancy once you've heard a heartbeat.
