Morning sickness??

I’m 12 weeks tomorrow and I’m no longer nauseous 🎉 but. Everytime I cough, yawn, brush my teeth, eat anything that takes a bit longer to chew (practically anything with my mouth) I gag horribly. Only threw up once because of it but mostly because I avoid any of the above. Has this happened to anyone?? Or am I just crazy? I’d rather not surprisingly throw up 😭
