My wife has severe endometriosis as well as several other pre-existing conditions. She was recently approved for zoladex to treat the endometriosis..she is supposed to have first injection in next few days. Today we were in the emergency room...she was slightly tachycardic as well as extremely low in iron and electrolytes..turns out she is pregnant. We r already scheduled for further doctors visits in next few days. She is 35 and has had several ectopic pregnancies as well as 3 miscarriages.
