Gagging during and after sex?

Currently 5w 6d and lately when I have sex with my bd it never fails, I start getting the icky feeling in my tummy and then before I know it I’m gagging in the middle of coitus and afterwards which I think ruins the whole mood 😩🙄 meanwhile he just starts laughing Bc he finds it funny 🙄

Anyone else experienced the same thing?

Idk what it is, I haven’t started having morning sickness yet 🤦🏻‍♀️🤷🏻‍♀️
