when did your babies arrive?

Ashley Lynn
Here are the stats for my children. 
#1- went into labor at 38+2. 27hrs of labor, "stalled at 3cm so they induced me"
#2- induced at 41 weeks, he was huge and we dealt with shoulder dystocia. 7hr labor. 
#3- born in her due date. Docs were worried about shoulder dystocia so they induced me. 4.5hr labor. 
I have #4 on the way and have been having contractions for 2 weeks. They never stick around. I'd like to think I could birth her without being induced but it just seems to me that since I've been induced 3x now, that my body is used to that? Insights?
