Am I Wrong ?

We’re currently TTC baby #2. And my husband is away for CDL school right now . I’m battling with myself right now because if and when I get pregnant I’d like to keep it to myself for a little while . Not for any selfish reasons , I’d just really like to surprise him with it. My first pregnancy , I really didn’t get to tell anyone myself because my lovely MIL announced it on FB immediately. Don’t get me wrong I wasn’t and am not upset about it , I know she was excited because my sister in law was pregnant too so she got two grandbabies but I just want to be able to surprise both my husband and her in a nice way AND be able to announce it myself lol.. is that wrong? Like I’m nervous that it may backfire like I was just hiding something from him. But he’s a very understanding guy so I don’t think he’d take it that way, but you never know . Someone please tell me this doesn’t sound selfish lol.
