hello, doctor i'm 28 yrs, and trying for a baby. my lmp was 18 july 2012, when my period was late by 10 days i took pregnency test it was negative. Dr suggested me duphaston for 5 days. but no period 8 days after stopped tablet. then i consult doctor he gave me gestone 50 mg injection now it becme 1 week but no period yet. i took beta hcg test it was negative. i'm confused having no pregnency why i missed my period.
