What would cause my period to be like this.?
I'm 21, my period is regular. I have bad cramps the first day, and then I'm fine. I've had my period since I was 12.
I'm 5 feet tall and 113 lbs.
Up until about 8 months ago, my period would be 5-7 days.
For the last 8 months it usually only lasts 2-3 days. It's regular the first day with bad cramps but by the second day I technically wouldn't even need a tampon because it's so light.
I am in good health as far as I know, not pregnant of course and no stds.
The only thing that's changed is I have gone from 128lbs to 113 lbs since January.
Is this normal? What would cause this?
