"if it doesn't interfere with other aspects of your life, it shouldn't prevent you from diving." That said, if you don't feel well, don't dive. If you do have problems with cramping or excessive bleeding, it's time to see the doctor (hopefully, a woman.) Hydration can be an important thing to consider, though. I'll bet your boss doesn't ask female customers what time of the month it is, does he? No need to answer that one.
