Trying not to panic...

Just had our 20 week scan and they found an anomaly with one of the kidneys. They couldn't see much else as baby refused to face them or move anywhere useful but said fluids, stomach, bladder and brain looked good. She couldn't say what might be wrong and we have to come back in two days for a fetal medicine doctor to look again.

She kept saying not to panic and to stay away from Google. Every inch of me wants to start looking at medical journals and at least have some idea of what *could* be happening. How do I last two days!?

Has anyone had anything like this? Have things been okay? What do I do?
