Is nausea and vomiting a PMS symptom?

Hello Ladies, I have a quick question please. I’m on CD 30 today with no AF. On CD 23 I had sudden nausea and I ended up throwing up, I thought it was the ice coffee and bagel that were responsible. So I stopped ice coffee for few days. Imagine my shock when on CD 28, I had nausea again and mild vomiting 🤮 , this got my attention because I had not eaten anything on said day. Again on CD 29, I had nausea and ended up vomiting my lunch. It was scary because I don’t throw up. (Like the last time I threw up was when I was like 13 or so. I’m 32 now) .I took a test few days ago but it was a BFN, and after the test the nausea and vomiting still continued so I wanted to know if this is a regular pMs for ladies. This is the first time this is happening to me.

Description of the nausea: it just comes suddenly from nowhere with the urge to throw up. The first two days happened in the morning. The third day happened in the afternoon. Now I’m a bit scared of eating. Pls share your experiences. Thank you.
