So I've lived at about 1,000 ft altitude for all my teenage years. Last August I moved to a place approx 4,500 ft high and I've had some weird thing going on with my periods. Off and on throughout my teenage years I've had period irregularies, but I can usually get it down to the week. Usually I go about 30+ days. Since at college, I have had only 2 periods in a 4-5 month time... Those two periods I have had have both been pretty light (like normal... maybe even lighter than usual) and 3-5 days long (which is also normal for me) I have also experienced what I think to be heavy vaginal discharge. Always feel like my panties are wet and sometimes change my underwear before the day is over. This has been going on for weeks. No itching though. I am wondering if it is just the elevation difference.. (I've never had sex, not taking any birth control or anything...) Thanks.
