Feeling dizzy

Idk why but I’ve been randomly feeling dizzy out of nowhere idk what’s causing it but In the middle of doing nothing I’m off balanced & lightheaded. It’s been happening for about a month now and I’ve been experiencing it atleast once a week.

Is it something to be concerned About? I always noticed it but idk what it can be a symptom of. Im worried at this point. Don’t wanna pass out in the street one day with my daughter.
