If you have endometriosis and you do get pregnant - either with the assistance of a fertility specialist or without - any symptoms caused by your endometriosis might actually improve. Since you won’t get your period while you’re pregnant, the monthly hormonal changes that affect the endometrial tissue will stop (a double bonus!). Your doctor will want to know if you have previously been diagnosed with endometriosis and may do some extra monitoring during your pregnancy. Because endometriosis can continue to increase in severity, some doctors may recommend not delaying pregnancy in case your symptoms and their effect on your fertility worsen.
