Dilemma

Lizzy • athlete• student• singer• in a reationship with pizza

My period is never on time and some times I'm gushing blood and have horrible cramps but the next day I dont bleed at all and on the third day I bleed. Also I have horrible acne and acne scars and nothing is working. I'm 16 being raised Catholic and they arent supportive of birth control. Is it right for me? Should I wait until im older?
