Hi, I have recently been getting one-day periods. I am a sexually active 21 year old, but i have never had unprotected sex. I m quite sure I m not pregnant, but i was wondering if this could be indicative of a serious medical condition? My periods are on time and I don t get any cramps or discomfort, but they only last about one day and one night. could this be a problem ? Recently I have felt like i need to urinate more frequently and sometimes i have problems with bloating . Thank you!
