Cervical mucus TMI

Hey everyone I don't typically do this but thought my cervical mucus looked a little odd. Yesterday it was thick and just white and today there was another type of mucus swirled in. I know everyone has different cervical mucus. I had the HSG done on the 5th of this month and ovulated the 12th of this month I'm supposed to start my period this Sunday. Does this look strange to anyone or like it could possibly indicate early pregnancy??
