<font color="green"> I have a 19 y/o daughter who is dd and vulnerable so we have her on birth control as a precaution. She gets a Deprovera shot every three months. An added bonus of this is that her monthly menses and her PMS symptoms are much reduced. I used Deprovera myself as a treatment for endometriosis. There is another pill out there being advertised as shortening periods but I don’t know anything about that. </font>
