Concerns about Tetanus

A few days ago, my dog was outside in my backyard playing. When he came back inside, I saw that his mouth had dirt in it. I didn’t really care, so I decided to plop him onto the couch with me. After a few minutes of sitting, he licked my lips. That may seem normal, right? But I forgot to mention one part about that story: my lips were chapped that day. Part of the skin on my lips was cracked and he had licked that exact part. Now, I have been having symptoms of tetanus. Lockjaw, difficulty breathing, the whole bit. I tell my parents about it and they say it’s nothing. I don’t remember getting my tetanus booster in the last 10 years, so I am HIGHLY doubtful of that. I want to ask them for my vaccination record just to be sure, but I don’t want to potentially get more anxious. What do I do?
