How can a woman fall pregnant without the semen of a man. There is no possibility. The bleeding: i also used injection for a few years and had not had any periods for that time, when i stopped taking injection, i bled for one month. Dr said, my body got alot of waste (coz there was no period, so blood did not come out of my body). So, i hope you got an answer.
