Thank you for writing to us.
I think that you have no problem. It is possible that sometimes the periods are irregular and sometimes they do not happen at the same time.
Do not worry and it is ok and after a while the periods will start to get regular. If they do not, talk to a Doctor.
Hope this helps you. All the best.
