Okay, so I've been taking the depo provera shot for about 10 months now. After 3 months on it I didn't have a period at all. Now all of the sudden I lightly bled for three days and then had heavy bleeding for half of yesterday and then today I've stopped. Is this normal? I keep my doc's appointments on schedule and I don't have ovarian cysts or polycystic ovarian syndrome or w/e.(sorry I think I spelled that very wrong). So I'm just wondering if this is normal at all? I'm making a doc's appointment with my "female doctor", hopefully I can get in next week. I'm just concerned something is wrong.

Thanks in advance. I kinda worry to much so if its nothing try not to laugh at me lol
