Not sure: Whether you're asking about the late menstrual period, or the negative pregnancy tests. Cocaine use can disrupt menstrual cycles, at least in rhesus monkeys and rats. http://www.ncbi.nlm.nih.gov/pubmed/9103482 Cocaine may also affect fertility, if you were trying to become pregnant. However, if you're using Cocaine regularly, your potential baby is lucky you're not pregnant.
