I won't even bother to tell you the stuff I'd done the night before I found out I was pregnant with my first.
Baby will be fine.
Allow yourself some time to adjust. Don't be afraid to let your lady know what you're going through. It's important that you keep the intimacy and communication going, especially at a time like this. Even if she seems happy or excited, most likely she's having the same thoughts that you're having.
Congrats!
