34 day cycle & no symptoms

We've had unprotected sex a few times this past month but honestly not sure if it was in the time I was ovulating. I did feel very wet down there at work and my sex drive has been very high. The last two months I got my period on the 25th. I have no pregnancy symptoms. This morning my lower back did have some pain for three minutes then went away. I've been feeling light headed. Idk if I should wait a couple more days or take a pregnancy test now.
