Thanks for the query.
Irregularity in menstrual cycles can occur due to many causes, like :
imbalance leading to intermenstrual spotting, delayed periods etc.
and strain can alter the menstrual cycle by affecting hormonal levels.
-Dietary changes and changes in exercise schedule can affect the weight and hormonal levels.
-Poly cystic ovary disease etc.
So, possibly you may get your periods soon.
By maintaing ideal weight, regular dietary and exercise schedule, regularization of the cycles can be achieved.
If same problem repeats, better to undergo ultrasound
once to detect possibilities like poly cystic ovary disease etc.
