Ovcon and first period

I HAVE BEEN ON OVCON FOR ABOUT A YEAR AND A HALF NOW AFTER TRYING OTHER PILLS AND FAILING TO REGULATE MY PERIOD. THIS ONE STARTED TO WORK. MY BLEEDING WAS LESS HEAVY(I WAS A SEVERE BLEEDER) AND MY CRAMPS WERE TONING DOWN ( I SUFFERED FROM SEVERE CRAMPS EVER SINCE I GOT MY FIRST PERIOD) BUT NOW THINGS ARE STARTING TO BE DIFFERENT. I HAVE BEEN TEMPERMENTAL LATELY AND VERY ANGRY. I HEARD THAT WHILE ON BIRTHCONRTOL PILLS, YOU EXPERIENCE SOME SIDE EFFECTS AS IF YOU WERE PREGNANT E.G. THE EATING HABITS AND NAUSEA. BUT I AM HUNGRY ALL OF THE TIME. I GET REALLY SICK IF I DON'T EAT. HALF OF THE TIME I CAN'T EAT WHAT'S IN FRONT OF ME. I FEEL SO NAUSEAED AT TIMES TO WERE I JUST WISH WHAT EVER IT WAS WILL JUST COME OUT. I'M TIRED ALL OF THE TIME. I'M CALLING MY GYN IN THE MORNING BECAUSE IT HAS GOTTEN OUT OF HAND NOW. I JUST HOPE THAT SHE CAN LET ME KNOW WHAT TO DO ABOUT THIS.
