Maybe baby?

Sooo I started ovulation week  on August 12th and that's when my boyfriend and I had sex and finished inside. Was supposed to have my period on the 31st but I'm 2 days late. I took a test 3 days ago because I've had baby dreams and my body heat at night rises to the point my boyfriend has made comments about how warm my body is. Is it possible that's it's too early to tell still or what?
