| | No period during summer?
I'm 16 and have had my period for three and a half years, but I have never had it during the summer. I am somewhat regular for the rest of the year, but for 3-4 months during the summer, no period. Why is this happening? Should I be worried? I'm not much more active during the summer, I spend most of my time inside studying. I have not had any weight loss or gain. I can't think of anything I do differently that might cause it to happen. I actually enjoy not having my period, I'm just a little worried something might be wrong. Any help?
