When Will I Get My Menses After A Laparoscopic Adhesiolysis And Myomectomy?

i had a laparoscopic adhersiolysis and myomectomy and adenomyomectomy followed by a D & C under GA to take out my fibroids on the 7th of January 2011 after which my doctor gave me a lupride depot 11.2 shot to debulk my uterus. I had my period last in the month of january which lasted for almost 2wks and up until now am yet to experience any period. i was told it is expected but for how long and is there any chance i could take in during this time despite not experiencing any periods?
