hello.

i went on the injetion last year and didnt like it. when i had to go back to my gp after 3 month i didnt continue to stay on it. ever since i went on it my periods are very irregular. ill have one for up to a week and come off it. 2 day later ill come on it again. its been like that since ive first went on it. i want to get pregnant but no luck so far. is the injection the reason why i cant concieve?

help
