6dpo and nausea ?

I’m 6 dpo and I was cramping quite a lot last night and today I can smell everything 🤢 I literally gagged bc I walked past someone definitely in need of a shower. The entire way home i couldn’t talk/move or I would have thrown up. The bleach they used to clean the inside of my apartment was a breaking point. I had to cover my face and run to puke. I know it’s still really early but I’ve never been like that before. Any help or personal stories would be greatly appreciated !
