Throwing up still TMI warning

I’m around 13 weeks and I’m still throwing up so badly. I couldn’t really eat too well so I skipped lunch yesterday (big mistake) and ended up throwing up bright yellow liquid (i assume stomach acid). My throat also started bleeding. My bf suggested I eat something so I ate some crackers and I threw those up, followed by more “stomach acid.” Kept down clear soup last night, but today I’m still nauseous with one puke episode (normal for me lately). My question is, how is this still going on at 13 weeks. Is this normal?
