Refusing one breast and sometimes refusing both

Ro

My baby is 4 months old and refuses to eat on my right breast. Like full on tantrum if i try😅 what do you all do?! Use your haakaa, pump, or just let it be?! Also sometimes like once a month she goes on a nipple strike she just screams at my breast for like 24-48 hours. Any advice on that as well?🤣
