Female cichlids that are carrying eggs will usually stop feeding while they have the eggs and babies. That is not normally a problem unless the female has multiple batches in a row. Then the females can starve. But one batch is normally fine. After she has released the babies, make sure she gets heaps of food to help her build up her strength.
Like @Colin_T Said she may have swallowed them Some of my cichlids would really stuff their mouths with fry. The first time they started having fry not many seemed to survived maybe because they were new at it but it did not take long before there were plenty of them. One thing I add to the tank was plastic fry grass. So the fry had a good place to hide.
Give it a little time if the fry are in there she will let them out and they should stay close to her for protection just make sure you feed her well! That is very important. You could also take them out and but them in a fry net. I prefer letting the mother take care of them. She will protect them in her mouth. It was really interesting to watch. There may only be a few so it may be hard to tell when they are in her mouth.
