Hi, please note that even in normal women with regular cycles, sometimes, period do get late & there could be a number of reasons responsible for that (
stress,
Anemia, recent
excessive weight loss or gain, strenuous exercise and also some diseases. All do not need treatment. I think you should evaluate yourself or take the help of a gynecologist to find a cause in your case before trying any remedy or else you may wait for sometimes for your periods to start normally & see if the problem repeats itself before trying any treatment. Best of luck.
