Question:
Is it permitted to conceive or get pregnant during these 9 days prior to Tisha B’av?
If it is, is it ideal, or generally better to conceive after these 9 days are over?
Answer:
It is permitted to conceive in the nine days, as it is a mitzvah, and there is no restrictions on doing mitzvos in the nine days. On T’ Bav itself it is not permitted.
