I have "OCD tendencies"?

so i have very bad paranoia, and after explaining it to my therapist, she said that some of my actions sound like ocd. like, every time i get in my car i need to check the entirety of it to make sure nobody is inside. and whenever i enter my room, i must check under the bed and in my closet. even if i leave for a few seconds, i have to check again. another is i always look behind me multiple times when i'm entering a certain friends house (just one friend, i haven't done this with any others for some reason)

i didn't get the chance to talk with her about it further and i don't know if i'm ever going to again. i don't know if it's ocd or just my usual paranoia. the actions are fairly recent; they've been happening for a few months, while the paranoia has been going on for much longer
