Egg implement pain or monthly cramps? 7 DPO.

I just started TTC. The past three days I have been getting these sharp little pains that last maybe 3-5 minutes at a time.they seem to be a little more towered the center of my pubic region and feels different then when I get my usual cramps. Which are most on my far right. Could this be a sign of pregnancy? Or is it just my monthly cramping? Or is it just another cyst? :-(
