PCOS and Pregnancy

Patient: I have PCOS and started a cycle for first in months on Jan 22 and had ovulation following immediately after.. I had intercourse 3x during ovulation period and started having pelvic pains, breast tenderness and discomfort, pressure in the right ovary area, and major back pains.. I have taken a pregnancy test and its negative but its only been a week and 3 days. My symptoms seems to be getting a little more discomfort in time. am I experiencing something else that should seek immediate attention other than possible pregnancy?
