text: is it possible for you not to have a period for yrs because of medicine you take? im also becoming more regular now.my family doctor didn't say anything,when my moma made this remark.i think she made it in front of him. you need to be a little more proactive when at the doctor's office.  ask the question, don't wait for mom to do it.  the doctor won't know you have missed periods for years unless you tell him/her.
