i was told that i need the shot every 3 months, which is almost due... since given the shot i only spotted a little in the end of april... 1 1/2 weeks ago i got pains off to the sides like i usually do a few days befor a period, but no period... given the closeness to the next shot date is this possible... my shot of depro in april was the first shot i have ever had of this medicine... if anyone can please help i'd greatly appreciate it... thanks!
