3rd c-section

Hey ladies. I need some advise. My husband and I are wanting to try for baby #4. I am a bit nervous because this will be my 3rd c-section. The other two went perfect but just nervous about scar tissue. Has anyone had more the 2 c-sections? I am also a plus size women and that also worries me a bit. I keep telling myself I have done it 3 times what's one more but you know just need to hear other people's stories. Thanks.
