Telling my husband I’m pregnant

Ok ladies I need all of the help!

A little backstory my husband and I have been ttc for ten years and I’m 95% positive I’m pregnant just can’t get a positive on a pee test so have an appt set up with my obgyn this week for blood test and ultrasound the downside to this he is in total baby mode and thinks I am too so he knows I’m over three weeks late knows I’m showing significant symptoms and even knows about said appt. Here is where y’all come in how do I tell him and still somewhat make it special after all of this waiting for the past decade I really wish he wasn’t so damned observant so I could have just a little bit of a chance of having one thing being normal and me getting to tell him in a cute way that might still surprise him. I told him I don’t want him at the appt but I’m pretty sure his stubborn ass is gonna be sitting in the parking lot when I come out lol so hit me with your best non conventional ideas
