Ultrasound today to check cord... vasa previa and marginal cord insert

Tr

Im 25 wks tmrw and I have a follow up ultrasound today to check on my cord. At ky anatomy scan I was told I have a marginal cord insertion. They need to check if it is velamentous or not which would mean part of the vessels are exposed. They also need to check for vasa previa which would be if the cord is over my cervix. If so they may end up putting me on hospital bedrest around 32 wks. Hoping thats not the case since I will miss my 4 yr old daughter so much but I will do whats best for me and baby girl.

Anyone have any experiences with this?
