If I´m asked "How many children are you planning to have?", is it right to say "I´m not thinking about it yet", i.e., can I use present continuous and yet in the same sentence? If so, would there be a more common reply?
In formal writing, yet in the sense "up to now" is normally used with an accompanying verb in the present perfect rather than in the simple past. Thus, one would say He hasn't started yet, not He didn't start yet. The use of yet with the simple past is common in speech and may be appropriate for informal writing.

I see. On the other hand, I know that sentences like "I don´t know yet" (simple present) are possible. My question is: instead of saying "The director hasn´t arrived yet", could I say "The director isn´t here yet"? Or instead of "Mom, Mary hasn´t started cleaning her room yet", could I say "Mom, Mary isn´t cleaning her room yet"?
How many children to have is something that people think about over a prolonged period of time. This woman (or man) hasn't been thinking about it; but one day she will be thinking about it.
It can apply to anything that occurs over a period a time:
A: We should eat more seafood. It will be quite cheap when we move to Redcliffe.
B: We aren't living in Redcliffe yet.
