Dear Ms. Ultrasound,
We just had our first ultrasound yesterday after hearing our baby's heartbeat earlier in the week. The ultrasound tech noticed what she called a rather large "fluid pocket" near the lower spine (see the attached picture). Neither the doctor nor her had ever seen anything like it, but they told us not to worry (that these sometimes come and go spontaneously) and to come back in two weeks.
We've been doing some research on our own, though, and found that these can often be caused by chromosomal abnormalities. Does this mean we likely won't have a normal baby? We'd really appreciate any insight you have-- the uncertainty is the worst part.
Without seeing the image I will have a hard time determining what was seen on the ultrasound. If this is something that the sonographer and the doctor had not seen before I would imagine it is not the more common neurotube defects, which may be what you had read about in your research.
Hopefully this fluid collection was not attached to the baby. Thats what it sounds like to me.
The follow up ultrasound will help determine what is going on with the pregnancy and if the fluid collection is presenting a danger to the baby. I know how scary it is when these kinds of things are found on an ultrasound.
Much effort, worry, anxiety, stress and anticipation is put into the possibility of a problem with an unborn child. My belief is that the least amount of worry a mother to be has, the better chance she gives her baby for a healthy development.
Please let me know if you have any other questions after your next ultrasound.
