Wedding

M
Ok so my best friend from college is getting married exactly 11 days after I give birth. If the baby come exactly on her due date. I am in her wedding and everything and told her that I am unsure if I can come.  Simply bc if the baby comes on time or later I will not be able to be there. However now if she comes a week early I still feel the same. 
The wedding is 4 1/2 hours away a from home and I would need to bring my sister with me to help care for the baby. I'm planning on nursing sono would have to do that every two hours. Any experienced moms out there think this is a possibility? The closer I get to my due date I say no but I really want to be there for her. Help what do I do. The wedding is May 9 and I'm due April 27
