Hi, I Took Plan B The Day After I Had

Hi, I took plan B the day after I had unprotected sex. Two days later, It happened again and I took a second Plan B. I have not had my period in almost a month and a half and I have been very bloated, dizzy, and nauseous everyday for about a month now. I've also been having some form of acid reflux and can't digest foods as well as before. are these symptoms normal? or are these more signs of pregnancy? or possible more severe problems? I have been so sick and I'm so confused by my symptoms. I've never felt so helpless.

Thank you very much for your information and help!
