I'm 23 and have been on depo for a year now, coming up on my fifth injection. I was told that spotting was normal for the first 2-3 injections, but my spotting has been every single day for six months now. Sure, the shot is convenient, but the spotting sure isn't. I'm convinced I need to make a switch. I have endometriosis, which complicates the issue a bit. Has anyone else had this problem and found something that works? I've been considering an IUD for the convenience, without the hormonal hassles - any thoughts?
