Suggest Remedy For Irregularities In Periods

I HAVE ALWAYS BEEN VERY IRREGULAR WITH MY PERIODS. I HAVE BEEN ON BIRTH CONTROL TWICE. THE FIRST TIME THE ONLY PROBLEM I HAD WAS MOOD SWINGS AND DEPRESSION. I STOPPED TAKING IT ABOUT TWO MONTHS ALONG. LONG STORY SHORT. ME AND MY BOYFRIEND OF ALMOST 7 YRS DECIDED IT WOULD BE A GOOD IDEA TO GO ON IT AGAIN TO TRY TO REGULATE THEM. IN SEPT 2009 I STARTED THE PILL AGAIN AND THE SECOND DAY STARTED BLEEDING. KEPT BLEEDING FOR FIVE WEEKS. I CALLED THE DR AND SHE TOLD ME TO STOP TAKING IT. AND EVER SINCE I HAVE BEEN EVEN MORE IRREGULAR THAN BEFORE. HAD ONE NOV 3RD 2009 SKIPPED DEC HAD ANOTHER JAN 7TH 2010 AND HAVE NOT HAD ONE SINCE. I HAVE AN APPT AT THE END OF APRIL BUT I CANT WAIT I AM SO WORRIED THAT I CANT HAVE KIDS. PLEASE HELP ME.
