The problem may be endometriosis
and the best way to decide is to have a diagnostic laparoscopy
where the inside of abdomen is visualised it shows the extent of endometriosis and any involvement of the sorrounding tissues. there are good medications available to treat endometriosis once diagnosed. It is definitely possible to conceive with this problem, but it is better to conceive earlier rather than delaying the pregnancy
. wishing you a good health.
