I'm freaking out!

I just need someone to talk to because tomorrow morning, I'm taking a pregnancy test. The first one since 2011. I'm so scared and nervous.  If I'm pregnant, how should I tell my husband?.. Or my daughter, she's only 3.. I'm freaking out over here. I'm excited yet scared. If it's positive- omg, I'll be happy. If it's negative- I'll wait for the right time. This wasn't planned so if I'm preggers, my husband will be quite shocked and so will I. We weren't planning on baby #2 for a couple more years. Again, the pull-out method isn't always reliable. Especially if your husbands a little drunk! I'm so nervous, it's making me nauseas. But I have a feeling I'm preggo. All the signs are there... Wish me luck!? Any advice would be awesome! Thanks!
