Sore nipples?

I’ve been on birth control (the pill) for 3 months. At the end of my 2 month pill pack, I took the placebo pills, had my period and then started month 3. I’m 2 weeks into the pill pack and my nipples are so sore. They’re always hard and hurt to touch. It’s just my nipples, not my entire breasts. Any tips?? It hurts to lay on them and sleep lmao
