Hlixian, endometriosis is common. Many of my frens has it.. I also have it.. My sister also has it. As long as we have menses, it will come easily .. The best way according to gyne, to prevent endometriosis from coming back (if you removed them liao..) is to get preggy, then breast feed .. Cos like that menses won't come .. Another is until reach menopause.. When I went for laparoscopy , gyne also remove the endometriosis in me (she said mine is still quite mild) , but good to eradicate them
Cos with endometriosis , will be harder to conceive (according to gyne).
How long did gyne ask u to take medication? Wat does the medication do? Did gyne tell you her course of action and follow up pertaining to your case? Don't worry

my sis was also trying to conceive but in vain .. Until gyne found she has endometriosis .. Once endometriosis is eradicated, she gets preggy and now is a mother of 2.. One 8 years old and another 4 years old

so take heart, you will get preggy once endometriosis is resolved
