I'm 24 weeks and I totally understand the "paranoia". I have a friend who lost her baby at 28 weeks with no symptoms whatsoever, the baby just stopped moving. I become overly sensitive about my baby's movements. But we have to understans that baby has sleep cycles too and we just have to relax for them to relax too. But if baby is not moving for quite a long time, iv read eating sweets will wake them up
Throwing up doesn't seem to phase them. And my Dr told me throwing up, at least a little, is a good thing because he said the hormone that causes the nausea is the hormone that helps you stay pregnant. I don't know if it's true, but it's definitely a nice thought.
