I had my periods on 28th July and had an unprotected sex on 9th September.That day I was ovulating as I have the symptoms of Pre-mensuration.The next day I feel breast tenderness & changes in my white discharge. There is no or little bit of white discharge on my underwear.After 2-3days I am not feeling that pain on my Breast.Is it possible that I am pregnant or should I wait for my periods to be skipped?
