im 15 and never had sex. i had my period 2 weeks ago, last week i had a super bad diet consisting of oily foods, barely and fruit or veggies, and lots of protein than i usually eat, i also didn't work out at all last week. this week i decided to start working out again, i usually do somewhat intense workouts then what i can handle, and after the workout i wanted to take a shower and noticed that there was a red discharge coming out of me. i was worried and looked it up and saw that i could be pregnant or have hormonal imbalance and lots of others, but i never even had sex. the day after i saw the red discharge, it changed to a brown discharge and lasted the whole day. im starting to get really worried, can someone help me?
