Thoughts on Going to wedding?

I have a wedding for my husband's cousin 11-19. I am due November 6th and planning for VBAC but know there is a high possibility of C-Section.  His parents expect us to go, but I feel hesitant about replying yes for both of us not knowing what type of birth to expect. I also have a 1.5 year old so between a newborn and a toddler, a wedding 2 weeks after doesn't seem realistic for us. If I have another c-section, I'm def going to need help from my hubby. I know if we don't go, his parents won't be understanding as they have offered other family members to babysit. It's a while away still but his parents keep bringing it up. Would you go if you were in the same situation?
