I have endometriosis. My doc has had me taking my pill continuously for the last 2 years. My last period was in February of 2003. This helps me TREMENDOUSLY because I no longer get cramps, but some day I will have to let myself get my period (if I ever want kids - i will have to go off the pill). I fear what my period will be like then. My doc tells me not to worry, but of course I still do....
