Possibly pregnant?

Ok so my man and I had sex a couple times in the first week after my period ended last month and recently I've had some dull soreness (and I mean really dull, almost like I did ab workouts a few days earlier but I didn't) in my lower abdomen like right between my hip bones. We used the pullout method and I was just wondering if this could be a possibe pregnancy symptom. I'm gonna take a test if I don't get my period this month, but like I said, I'm just curious if this could be a symptom
