I have started swimming 2 months ago, I went for swimming wearing tampons during my periods last time but my periods got delayed by exact 1 month. Though I am taking high amount of protein daily i.e. Soy milk, dates, black raisins, almonds, fig, walnuts, sesame seeds, melon seeds, flax seeds, sprouts, green tea, cow milk, juice and meals are included in my daily diet. I do skipping, Yoga in the morning and swimming in the evening. But still I am wondering about the cause of my delayed periods. Please let me know whats wrong with me? I don t have any other health issues or ongoing medications.
