The Pill... HELP

Really, I need to go on the pill. I have have awful, painful periods and I have bad acne which makes me ridiculously insecure. I wear makeup but I'm still very unhappy with myself. The issue is is that I'm scared to go on it, I'm worried about the side effects and how bad it is for my body but I know I need to go on it ideally. Can anyone put my mind at ease? I really want it but I'm scared. Please, no hate and thank you ladies for your help 💓💓
