Had a scan done at 13 weeks which showed fluid around my baby's head and abdomen. They didn't say how much but doctor thinks it maybe chromosomal or otherwise. I'm almost sick with worry and scared of losing my baby as I've had three miscarriages before and this is the first time I've ever gotten this far along with my LO. My doctor has said that it is likely though that we'll not make it to term

An amnio was suggested to be done in a few weeks time to check for chromosomal abnormalities and the like. It seems like an eternity until that day comes
Re: Fluid around baby's head and abdomen
If your doctor is a regular OB, then I would ask to be referred to a specialist. Also, if you'd have to wait on amnio is CVS or a cell free DNA test like Materna Plus an option right now?
Thinking of you and sending positive thoughts and prayers your direction.
