so last month in December , instead of having a period , i only had brown discharge . it wasn't a lot though . i had period symptoms all through the month , but no period . only spotting . this month , is also the same way . ive had symptoms but no period . only brown discharge . i thought the reason i missed it last month was bc i was under a lot of stress . this month , ive tried to keep the stress at a minimum . but im been working out this month , about everyday , and i heard excessive exercise can delay your period . but i haven't been doing any hardcore workouts . also , just so you know , i haven't had sex & im 14. so can someone pls help me calm my nerves about my period not coming ?
