Not to worry

Hello, Irregular periods are common. You just need to have a healthy diet, do regular exercise and reduce stress for your emotional, physical and mental well being. You can also visit my clinic International Fertility Centre located in New Delhi for further examination. My clinic offers varied gynecological treatments and services and ensures that you have a successful treatment. You can share your contact details to reach you.

Nothing you should be worried about. It's a small variation. Periods may be affected by many factors- stress, exercise, diet. If you have no other complaints, I don't see a reason to worry

Cycle varies with age and other environmental factors, so until other symptoms also appear, 2 days of cycle is good enough.
