Hi! I'm looking for 2 specific Omega!Cas-Preg fics (Destiel)

1. Cas is pregnant but afraid of telling his Alpha-mate/pack leader Dean. Cas is bruising easily (which only happens if the Omega is vulnerable to another Alpha and/or pregnant). Beta Sam figures it out bcoz Cas smells like he's in heat. Dean finds them both in the kitchen when Sam is sniffing Cas' neck, thinks they're having an affair, shifts into a wolf and attacks Sam. Cas also shifts into a small black wolf to save Sam and gets hit on the stomach. That's how Dean finds out he's going to be a dad. Happy Ending.

2. Cas is pregnant but doesn't want to tell Dean coz he thinks Dean doesn't want the kid (yes, it's a pattern, I know!). He tells Benny, who accompanies him to the Ob/Gyn. Dean somehow finds out and Cas confesses he's thinking of moving in with Benny until and after kid is born. Later he finds Dean crying bcoz Dean thinks Cas doesn't want him around their baby and Cas confesses that he thought Dean didn't want it. Happy Ending.

Both these were on AO3, tagged under Mpreg and/or Omega Cas, but for the past 3-4 months they seem to have been lost (at least I can't find them). Does anyone know if they've been moved/deleted or I'm looking under the wrong tags.

Please and thanks in advance :)
