I'm not a lawyer and not an expert in this subject. I saw the news of people not being able to get their parole related docs. But your wife is married to you, US citizen. Even people out of status can get GC if they're married to US citizen, as long as they entered with inspection and don't have other bars to adjustment.
Not receiving NOA just yet is normal. I'd give at least 4-8 weeks for it to show in the mail, this is normal timeline. You didn't even have 2 full weeks since filing. When did application arrive to USCIS? I bet it took few days...
