hi i think like before its just skipped period and this could be from this extra work load you have been doing and including the exercise. if your not getting any pains or any other signs. just see how it goes. do hope this helps. good luck
i'm 20 and i've missed a period. is that normal? . my period is usually irregular--once in 9th grade i missed it for 3 months. i'll be 20 next week and i've missed my period this month. the first week of april i did a lot of work/exercise that i don't usually do but i haven't done it since then. also about three weeks ago i completely cut caffeine from my diet cold-turkey. also i'm a virgin. i've never done anything sexual.
