Pregnant with period?

Patient: About two months ago my fiancé and I had unprotected sex. Since then I have had two really light and short periods. Even though I have had my period is there a chance I could still be pregnant? The only symptoms I have had is tenderness and swelling of the boobs, dizziness, and being bloated even after my period was over and some nausea.

Symptoms: Tenderness of boobs/ nipples, dizziness, bloating.
