Should I go off?

I'm 31 and have been on bc since 16 or maybe 17. I wouldn't have a regular period. At 20 I wasn't sexually active and decided to go off for a while and didn't have a period for four months. Well now I'm a little older and have acquired some other physical issues along the way. I'm trying to eliminate some medications and thinking birth control bc I'm sooooo sensitive and crazy when it's that time. But I just became sexually active again and if I go off birth control and don't have a period I'll never know  unless I always take a test. The thing is I can't have a baby with the certain meds that I'm on. Q should i go off to try to eliminate some meds and see if it helps my hormones/acting and feeling crazy?????
