Welcome to ATD.
Thank you for the query.
Cocaine effects the sperm and passes the blood brain barrier. The man's sperm effect the body chemistry and the babies development. Even if you have a normal baby if you continue to use cocaine, he/she might develop mental problems or addictions as an adult. It is best for you to quit cocaine consumption completely and then plan your baby.
But if you really want to plan this month, make sure there is a gap of at least 5 days between cocaine consumption and sexual intercourse.
Hope this helps,
