USPS lost mail but no tracking? HELP?

So I sent a package to my friend in NY by parcel post from CA. I sent it to her on 6/18 but she still hasn't received it yet.. it's been 2 weeks. I don't think that's normal? Not sure what to do/what I can do because I also did not have any type of tracking/delivery confirmation/insurance on the package.. IS there anything I can do?? Please help! Thank you in advance ):
