please help! i'm a healthy 23 year old female. however, over the past year i've been experiencing some changes in my menstrual cycle. a year and a half ago i miscarried at 10 weeks. since that time, i have had several bacterial infections and my periods have become more spaced out. normally, i had 28 days between every cycle. lately, i've had anywhere from 35-38 days between my cycle. over the past 2 weeks, i've experienced chronic headaches, dizziness, hot flashes, and nausea. does anyone have any information that may help me? i've set up a dr.'s appointment, but can't be seen until august!
