How should I tel my fiancé were pregnant?

I have to take a second test, but I took one when I got home from work this evening and I got a positive pregnancy test. I’m scared and excited and also nervous and happy and a little panicky. My fiancé and I both agreed we should wait for kids (even though I have crazy baby fever), but lately he’s not been nearly as careful as he usually is, but is still saying he doesn’t want kids just yet. I’m going on nine days late at this point and there are definitely two lines.

How should I go about telling him I’m pregnant when I know he’s not ready?

I know everyone says that if you’re not careful you get to deal with the consequences of your actions, but I also don’t want him to get freaked out or panic either. I’m ready to take responsibility, but I’m still nervous about how he’ll react.
