Scared please help

So I have been sick with a severe sore throat and white patches on it for 3 weeks now the first week I went to the doctor they said I had strep I took my antibodics and started feeling better but continued to finish them as I was told. The second week my throat was swollen and stuff again I went to the doctor strep test came back negative do they blood tested me for mono. It came back negative. So they gave me a steroid shot and meds and sent me on my way. This is the third week I'm sick and my throat swollen with white patches. I recently found out I guy I had sex with had given another girl chlamydia. Not sure if it was before or after. That was about a month ago (no I did not have oral sex) could the two be linked together?
