Pregnancy cravings 😝

This is my second pregnancy and I'm onky 9 weeks but I can definitely say that I'm having craving like crazy. I didn't really have any when I was pregnant with my first and never understood the "cravings" everyone was talking about. I just ate normal and maybe once in a while wanted French fries but that's normal for me I love French fries. But this time, all I have to do is hear someone say a particular food and I want it BAD. Watching commercials in tv is hard. My mom always says to eat what I crave but if I did that I'd be constantly eating EVERYTHING lol. Anyone else experiencing this? Is it a sign of something else?
