Am I pregnant???

My periods have been regular ever since I started having them 10 years ago. Even after pregnancy & almost 6mos after a miscarriage. My partener & I last slept together 10/8/2014. I'm not on birth control & we used withdrawal which seemed very close because I felt his ejaculation all over and not sure if he pulled out right away. My last period was 9/17/2014. My cycle is 27-28 days every single month. Never late. My period this month was due 10/15/2014. But nothing still. Just tons of bloating and full breasts and huge appetite, increased cervical mucus. I took a test on the 16th, it was -, today was also -. What do you ladies think??
