Do I possibly have OCD?

There are many types of symptoms in OCD. For example, me, like you, I dont worry that much about germs and my room is very messy. But I'm a hoarder(maybe thats the reason my room is so messy). I cant throw away things and I have kept things since I was probly 5 years old and I;m 18. And I have to check things obsessively (like 20 times) but I still have OCD.
