I and my husband have been trying for 3 months now. We had unprotected sex every day this month right after my period was over. I am a week before my period is supposed to start and I am having menstrual like cramps, but my breasts are not sore like it usually happens and my stomach is not swollen also. It seems like the only symptom I usually have prior to me period is only cramping. I am also having cramps on my left side near the ovary... could I be pregnant? How long should I wait to do a test?

It sounds as though you may be gearing up for a period. You need to wait until your period is missed before testing and make sure you use first morning urine to test.

I can feel light cramping where my ovaries are before I start my period.

As j_9 said... wait until your missed period.
