Not ovulating

Emily
Been given the heart braking news today that I'm not ovulating, we have been trying for 5months, been off the pill for 14months. I went to the doctors with concerns in August that my periods were so light, originally told to wait a year after being off the pill but I went back after failing to conceive aswel, now Iv been given the news I don't know what to do,. They want to test me again in 3 months but I honestly feel it's pointless I new something was wrong with my body because my periods wernt normal, so now feel the extra test is pointless. Has anyone else experienced similar? If so what's the next stage? Any advise will be greatly appreciated xxx
