You are probably feeling the effects of the hormones you are taking. It's really too early to be feeling anything as a result of a pregnancy. Implantation normally takes place about 5-10 dpo, but even after that it takes a couple of days for the hCG (which is what causes pregnancy symptoms) to build up in the blood stream.
