I'm 7 months pregnant, is transitioning to a keto life style safe this far into my pregnancy?

Hmmm....: Normal, healthy women do not have to alter their foods and drinks while they are pregnant, as long as their diet is a healthy, natural diet that doesn't contain items that aren't good for a developing baby (such as fish with higher mercury levels, etc...). Prenatal vitamins can be taken. Probably not a good idea to "try things" during pregnancy. If something goes wrong, some little baby suffers.
