I just started churning, and I guess I screwed my chances like a noob! Well I am a noob

Two weeks ago, I applied and got instant approval for citi TYP for 50k.
Last night applied for AMEX HHonors for 50k, instant approval.
Last night applied for Chase Marriott for 70k, instant approval
Then I got a weird itch to apply for Chase Hyatt, and I got the message that they need more time to review my app!
This morning I called the automated app status and it said both my apps are pending and will send me their decision in 2 weeks!

Does this mean they may even decline Marriott that they approved?
What should I do now? Should I call them or wait for their decision and then call for recon?
