Was anyone pregnancy a huge surprise!?!

I found out 3 weeks ago I was pregnant. I told my husband right after I found out. He says he's excited. I am still trying to figure out how I feel. I wasn't expecting this. I just need kind words to get head wrapped around this pregnancy. Is anyone going through the same emotions?!? We have haven't said anything to anyone and I don't want to say anything until I know for sure how I feel about things.
