Could I still be pregnant?

Patient: Hello. My name is Ashley. I am sexually active and have unprotected sex often. At the end of August, I had unprotected sex with my boyfriend. A few days after that I spotted for a few days. By that time, it was September. There was no more blood for the rest of that month. In October, I bled for about a day at the beginning of the month. My periods are usually always regular and occur at the beginning of every month. Last month in November I did not bleed at all. It is now December and still no blood. As of December 5, I am late for the month of December. I took two home pregnancy tests, both negative. I went to planned parenthood today, and the test was negative. I also have a white milky discharge from my breasts. Is there any possibility that I could still be pregnant?
