Is this serious?!

Me & my husband have been trying to convince for 14 months exactly. I have not taken any pills or shots or any type of Plan B medication, my baby just turned 4 yesterday, I thinks it's about time we give her a little brother or sister but it is just not happening. What is happening is that from a size 5 that I was I am now going to be a size 11! I am starting to get worried. :/
