Hello mam, thanks for trusting health care magic.Endometriosis
is a disease which affects all levels of conception and also the quality of eggs and embryos if produced.
But the severity in your case though seems to be less as per the ultrasound
findings but ever since you havent conceived so far despite of being on induction drugs in my opinion you need to get a diagnostic laparoscopy
In case you have further questions you can consult me on health care magic forum and i will be happy to help
Take care and wish you all the best.
Dr Manisha Jain.
