I just got my first Depo shot 2 days ago. I got it because of irregularly heavy cycles with tons of terrible cramping. Along with spotting in between cycles and cramping in between cycles... as well as really large blood clots. I'm 28 years old... after reading about it I'm not sure if I should get the next shot or not... there's so many mixed reviews... I have had some soreness on the injection site... NO mood swings... NO anger... NO feeling down... I had some spotting at the start of the shot but the same day I had an endometrial biopsy done, so it was probably because of that. I would normally start my cycle w/in the next 3-5 days. I am anxious to see what happens. However I'm nervous about 3 months from now, when it's time for my next shot... how do I know if this is for me, or if I will have negative side effects... or will I ever know? It seems like some women didn't have any side effects until after... ugh. HELP!
