Am I pregnant?

Patient: I had unprotected sex on Tuesday 17th of December and Thursday 26th of December. I had missed my pill on Monday 16th and continued to not take it due to concerns of maybe falling pregnant.The past few days I have had nausea, stomach cramps, change of appetite, headaches more often than normal, very sore and tender breasts, lower back pain and feel like I need to urinate more.I am wondering if I might be pregnant and when would be a good time to take a test?
