Could i have an std/sti?

did oral on man dec 11. 4 days later got a pimple like sore inside lip by canine/incisor teeth. went away over night. about 2 days later i got another on the other side, also went away over night. it kind of looked like it had a white head. then i got flu like symptoms (sore throat, cold, headache, kind of nauseous but not really) that lasted 4/5 days. then a few days later i got a canker sore thing. it went away over night as well. my tongue is yellowish which went away for a day when i ate no sugar. now i have another bump which is not open this time, and is more like just a hill type bump which is already going down after a day. it had fluid in it. i also french kissed him and he has pretty chapped lips often. STD/STI?
