My fiance' and I just got engaged and the wedding is 17 months away. However I'm almost 6 months pregnant and am trying to get all of the planning done in the 4 months I have before I give birth to our baby. I don't want to have to plan a wedding, finish college and take care of a newborn all at the same time. I know who I want to be my bridesmaids but should I go ahead and ask them to be in it so that I can continue to plan and know that I am planning for the right amount or should I wait until closer to the wedding and then adjust my plans?
