Am I out?

Due to my and DH’s work schedule, we haven’t been able to BD as much as we would have liked (the 4th). We had plans to have intimacy on the 11th, but I had a car accident. I haven’t been in the mood (due to being so sore). The hospital ran a urine pregnancy test that resulted in a negative. I was only maybe 4dpo at the time.. Am I out this month, or do I still have a chance?
