Throwing up yellowish/greenish liquid

Hi guys, this is my first pregnancy. Im currently 7 weeks and for the last few days I’ve been so nauseous and only vomit at night. The first two times it was yellow . Just now it was a dark green and from what google tells me its called bile and is because it’s on an empty stomach.

Now here lies my problem. The first day i figured was because I wasn’t eating enough , so the next day I ate a bunch but it didn’t seem to help instead it just felt like it was piling food on top of each other waiting for it to erupt . But then hours later that night I throw up 🤷🏽‍♀️ no food just bile. And same thing tonight I just don’t know what to do at this point.
