I know this is kind of off topic butttt I recently became sexually active and have used mutiple forms of contraception, none being prescribed birth control tho. i havent had sex in the past three days and i lost my virginity about a week ago. my nipples have been sore for the past couple of days and im so sure im not pregnant but idk what else could be the cause. maybe hormonal imbalance? i havent beem wearing super loose fitting tee's and its not the same kind of rashing that would be caused by loose clothes, its actual tenderness and slight pain when touched... Anyone else experience this before?
