Restore contacts

If you go to the computer and log into iCloud there, do you see all of your contacts? If you go to Gmail, what contacts do you see there? Are they the ones that appear to be missing from iCloud? I'm thinking you have more than one group of contacts now, some in iCloud and some in Gmail. Make sure when you go to Contacts, you check in the upper left corner to see if you have All Groups, or All Contacts checked.

Well, to start with, how are you managing your contacts, with iCloud, another cloud service, an email service, or do they just exist on your iPhone? What were you doing when you "lost a bunch of my contacts"?
