Planning baby number 2, before or after wedding in 3 months?

I'm getting married in the beginning of November. I have very bad baby fever and want another little one so badly. I am also scheduled to have my period during my wedding and half of my honeymoon. I want to start trying now to conceive, but am scared that I will start to show early with baby #2. My friend is pregnant with baby #2 and is 13 weeks and looks how I did when I was 17 weeks. I'm asking for your advice and past/current experiences ladies. No negative comments please, they are aggravating and annoying to read.
