Memory loss in your 20's?

I don't know if i'm just paranoid but is it weird to become really forgetful in your 20's? I haven't always been this way but lately (within the past year) i've been much more absentminded. I forget words/names for things a lot. I know what I want to say but sometimes i just can't get the word out. And I also forget things I said to people even if it was just a few seconds before. I forget things I did during the day. My friends will remind me of something we talked about months ago or things that happened and I won't remember until they completely spell out the whole event. These things usually come back to me but it happens so often that I'm wondering if I'm just an absentminded kind of person or if this is something worth talking to a doctor about.
