Sex trafficking or am i paranoid?

Recently since school has been out I have been going to the store more often during the day, I notice A LOT of men with babies in strollers or toddlers in a cart. Which obviously i wouldn’t think anything of but i kept seeing them, and they were kind of circling me. I’m 5’3 and 140 pounds. I got very nervous and got my stuff and left and of course was very careful leaving the store and getting into my car. Thoughts? Anyone else noticed this?
