I tried 7 months to have bb, but still not successful. Moreover, the M cycle in these 7 months was not very consistent, sometime 34 days, sometime 30 days, sometime 36 days. Then, I went to Dr. Che. After two months medicine, the M cycle dropped back to 30 days. In the third month I succesfully conceived a baby. I also used ovulation test paper to help. Hope it will help you. you may also PM me if you still have further question.
