You cannot get pregnant after your tubes have been tied, clipped and burnt. This is because the fallopian tubes are actually burned to close them. The only time you can get pregnant is when the tubes are not burnt but tied only.
Yes you can!! My best friend had hers done after having two children and her youngest is now 6 just earlier this year she found out she was pregnant in her tubes!! Even though the pregnancy was terminated she was still pregnant after having the tubes ties and burnt!!
