Sharp, throbbing intermittent pain?

Ana • Both me and hubby are 28. We have one beautiful girl!
I'm 5 w 4 d and just started having these very random, sharp, throbbing pain very very low abdomen, like almost just above the vagina. They only last about 1-2 minutes and have happened twice today. Pretty uncomfortable but no bleeding or anything. Anyone have this?? Is it stretching????
