WTF IS GOING ON WITH MY BODY

hey guys so i am 16 and i have been on sprintec (hormonal combination pill) for 5 months now. last month i messed up my cycle i missed a pill but i got my period and started a new pack. ever since the new pack my boobs have been killing me and i’m more bloated than usual and i have killer headaches, heartburn, and even acid reflux. (all things i never have) i took a pregnancy test just cause i was scared something bigger was happening even though i’ve taken my pill perfectly the whole month it was negative. any idea at all what’s going on with my body ?!
