1. If you make Serana or any follower NPC wait in one spot for too long they will always eventually LEAVE that spot and head back to wherever they consider 'home'. If it's your wife follower she'll head to the house you currently live at. If a Dawnguard follower she'll head to Isran's fort. Mjoll will head back to Riften unless she's your steward or you've made her a Blade.

2. Serana -- she'll either be at Fort Dawnguard, or... on a recent playthrough I couldn't find her anywhere and used the console command to send me right to her, she was at Castle Volkihar in the main dining hall. I have no idea why she went there but there she was. This was after the Dawnguard MQ had been completed, the non-vampire route.

3. Try fast-travelling a few times. Try entering a cave or a ruins, then exiting, and again. Try another fast travel this time to a city.

4. Still no luck? Fed up with running around looking for her? Then as a last resort try the console command:

(open console: ~) type in: player.moveto 02002b74  (hit enter)

That will take the player directly to her location. Note: the "02" at the beginning of Serana's ID code might be different for different players. For yours you'll have to do some googling or wiki searches.

since you finished the main questline of dawnguard, serana will be with the dawnguard because she's aloud to be there
