Am I wrong/overreacting?

So my bf and I took a pregnancy test and the test was a little unclear. I said I think I seen a line faintly & bf said he didn’t see any line. So we agreed to just take another one in a few days & left it at that.

So we get into bed and he’s like “I wanna ask for a second opinion” but he says this eagerly like a kid excited to tell a secret & I got a little annoyed b/c I knew exactly who this “second opinion” was. His female best friend. Don’t get me wrong I have 0 issues with the girl but I feel that certain things u should just keep within your relationship. Like if we JUST agreed to take another test in a few days why are u already thinking of including her in our fucking business. God forbid she said yes she sees the line, now she’s the first one to know I’m pregnant ??

So I told him no, we’ll take another test in a few days & go from there. We don’t need no second opinion about anything. He said okay & assured me he’d never go behind my back and do something like that without asking me if it’s okay first. But I’m just a bit annoyed because why is your first thought to tell her? In the very beginning of our relationship it wasn’t the best & I know he told her alot so I just feel like stop telling her shit about me. Is she running to u telling u all her relationship issues ? No .

Am I overreacting/overthinking?
