Can you get pregnant after a endometriosis surgery?

If your ovaries are gone then there are no eggs being produced, now if I misunderstood your question and you still have your ovaries yes you can become pregnant although with you being on the pill assuming that your taking it correctly it is a very slim chance that you become pregnant although if you have skipped a period and are worried that you are pregnant take a test ASAP or talk to your doctor and see what is going on so that you can do what needs to be done...Good Luck and God Bles!!
