Help please!

Hey! so here’s the sitch— lately i’ve been getting SUPER bad acne all over my chin and like kinda between my eyebrows...i’ve assumed it would go away but it hasn’t... it’s getting worse! (I wash my face regularly with a whole big system) i’ve been told the pill will help with acne? problem 2: My period is so irregular and i’m so so super self conscious of it and worried about it! I never know when my period is coming so that’s stressful but more importantly I’m the type of person who wants to have like 5-6 kids when i’m older and i’m so so so so scared that i will have issues because of my period being so messed up! ive also heard the pill can help with becoming more regular? Should i start to take the pill? i’m 16 and not sexually active and honestly don’t plan to be for a while haha but please let me know what you think! and what consequences there might be?
