Anyone had 4 C-sections?

I have 3 children eldest 9 years, then one 5 years and youngest is 2 and a half, all born by c-section, I would love to try for 1 more baby. but am so scared because the risks are higher with your 4th. so i would love to hear from other mums who have had 4 c-sections. is it a good idea or a bad one? I would also get sterilised if i was to have a 4th.
