If the "pregnancy" here is related to worms, the tags list is wrong. The word pregnancy does not fit here, this is incubation or oviposition, but not a real pregnancy. I hate it when tags try to deceive people.
A strong suggestion, create tags for oviposition and incubation, because these things are not real pregnancies.
