little confused here. help lol

Ok so I had sex with my bf on 11/4 (ovulation day I think). so I'm 9dpo. I've been having these weird symptoms but my main one is, feeling like throwing up . I'll eat what I normally have but after that I have that "uuugh " taste on my throat. hopefully it makes sense. and another thing is that "bubble sensation from your chest to your throat ". last tests I took were negative. it's been 3 days since I took a test. I will buy some test tomorrow 😊
