Got my BFP yesterday and I'm so excited and nervous. Any advice for a newly pregnant woman?

My husband and I decided we wanted to try for a baby right after we got married. We got married Oct 31, 2008 and I just found out yesterday that I was pregnant. I was shocked that it happened so quick. We only had 3 times in the month that we were trying and managed to get pregnant. I'm considered obese by doctors so I really thought it would take a while. Now I'm really excited and nervous about all this. This is mine and my husbands first baby. Do you have any advice for newly expecting parents?
