If you are sexually active, pregnancy is always a possibility. However, these symptoms can present for reasons other than pregnancy.

Since it it is too early to take a pregnancy test, for now treat yourself as if you are pregnant. Get plenty of rest, eat healthy, avoid tobacco and alcohol. It might be wise to start taking a multivitamin that contains folic acid.

Even if you were pregnant, your body hormonal changes so far would probably not be the reason for your symptoms, they could arise from many things. If you became pregnant on the date of ovulation, you are still talking about a small blastocyst, not even an embryo yet.
