my mood swings are all over the place and im usually quite moody most of the time which is out of character for me. my periods are all over ranging from two weeks between each one and 6 weeks was the longest and i never know when i will be due one month to the next. also i seem to get painfull alot and they sting whenever they are cold. is there something i can do or take to help controll it?
