When does morning sickness and cravings start?

I know it’s different for everyone but just in general, I’ve been praying I don’t get morning sickness because I’ve got a super weak stomach already.

I had a weird dream about twizzlers and once I purchased some I didn’t even want them 🙄 I was told it was “too early” and it was all in my head so I’m just curious on other people’s experiences.
