I had unprotected intercourse on 25th august and took unwanted 72 within 2 hours of it. But my periods didn't come on 3rd september which was my expected date so I took a pregnancy test on 6th september i.e 2 days later of my expected period date (3rd september). It was negative. But, can you tell me why i'm having the breast tenderness and frequent urination symptom. As these are early pregnancy symptoms.
