sickness

so as you can see i’ve had sex since i️ve gotten off of my period & ever since wednesday the 22nd every morning i’ll get up and feel so nauseous and nothing will help it but sleep. i’m on vacay in mexico with my husbands family & i’ve been here a lot so i️ know it isn’t because of the environment... i️ went to the dr today & i️ have strep with the highest fever but still feel so nauseous... i️ didn’t get a pregnancy test because i️ feel like it’s wayyy too early.. what do y’all think?
