Should I Take 'cabergoline' For Prolactin Producing Microadenoma?

Hi I am 31 i have been diagnosed with Prolactin producing microadenoma in 2005, was taking Cabergoline 250 mcg twice a week (half tablet) for last 2.5 years, prior to that i was taking Bromocriptine for about 3.5 years, on 13 June 2011 doctor have decided to take me off the tablets for 3 moths, prolaktin results on 15/09/2011 is 3500 but only appointment i can have is 21 of November 2011 so next 2month. What should i do? should i start taking Cabergoline back? I have problems with my period, now 3 weeks overdue (usually that was week to two weeks).

Many Thanks
