Psychics?

This random stranger stopped my boyfriend and me as we were walking out of the store today and told me that I am pregnant! Surprised and confused I asked him back, "I'm pregnant??" And then he responded by telling me, "you betcha you're pregnant, check and I can assure you you're pregnant." 
In the car my boyfriend and me were trying to make out what to think of what the man said.. My period is a little bit over a week late... but this whole year my period has been funky so I didn't think much of it when it was late, now however I'm nervous! 😃😬 
What do y'all think? Would you believe him? Do you think there's people in this world with that ability to tell things like that even if they don't know you?
