I thought I was over morning sickness

Jess • Been with the love of my love for almost 8 years, married 17/08/19 baby boy 💙 👶 05/10/2019 baby boy 💙👶 April 2022 baby girl 🩷🧒 March 2024

I’m 18 weeks 5 days I haven’t had any morning sickness for about 4 weeks nothing. Then tonight I had dinner & it all came back up I brought everything up & also ended up with a blood nose half way through. Is this normal? Can it just re appear after nothing?
