Oral sex concern ????

Today is Sunday, and on Friday and Saturday , I have gave my boyfriend a blowjob. Yesterday I was perfectly fine , but last night , after giving him another , I started to get a little tiny bit of a sore throat, and I figured it would go away . But when I woke up this morning , it was worse . And it still hasn't gotten any better . Maybe it's from deep throating too roughly ? And it irritated my throat , but my tonsils are swollen and do have spots of yellow & white on them, should I be concerned ? And vist the doctor for a possible oral STI? Or should I wait and see if it goes away? My patented continues to say he doesn't have anything and he's been checked . But I'm not sure if I entirely believe that. Advice anyone ???
