I have been on the depro Vera shot for a little under a year when I first started it I had some minor bleeding for a while but it stopped and my periods stopped also I havent had any periods or spotting in 5 month until today after an argument I began bleeding it was short and heavy it concerns me because it was so random
Hi. Thanks for asking in Chat Doctor. Alteration in period cycle, heavy bleeding or minimal flow after a depot proverb shot are common. Depending upon the individual, progesterone in the depot preparation can result in either too much or too little flow.  Also, the menstrual cycle will be erratic and that's why it is not suitable in young girls. Progesterone can also result in mood swings. Premenstrual tension may the reason for your emotional outburst. However, the failure rate of progesterone depot is minimal, and it is very effective in preventing the conception. But if the flow is too heavy, then you should consult a gynecologist. I hope this is useful to you.
