Miamoo,
See this article:
C-Section or Not? Choosing a Caesarean Section Delivery to Avoid Incontinence
http://www.healthcentral.com/incontinence/c/52/19010/section-avoid
In particular, note where Dr. Sobol writes:
"Having a c-section does not guarantee that you will not have incontinence and having a vaginal delivery will not doom you either. I have many patients that I see for stress incontinence because of pelvic floor relaxation and urethral hypermobility that have only had c-sections, or have never been pregnant. On the flip side, not everyone who has a vaginal delivery will have stress urinary incontinence."
I hope this information is helpful to you.
Best,
Maria
