I am going insane

Last week i got 2 positive test And then il negative one since then. My cycle is 9 days late and I've even had blood work that is negative. However I am so nauseous in my breast hurt so bad and I cannot intake alcohol without feeling like crap .And im burping so much. This happened with my 1st pregnancy. I really feel like I am pregnant but or maybe just hormonal issues? But I'm not getting any help from my doctors and feel like it's pointless to even say anything at this point . I have not felt like myself in about 2 weeks. I even have random gagging. I just dk.
