Absent period

L
I'm 14 and havent had my period for 11 months. My mom knows this. I've only had 2 periods but they were about three months apart. I don't know what to do. Has anyone else had this? Are there any natural ways to get it back? I don't get any cramps or anything, and this might not have anything to do with this, but I think my breasts have stopped growing too? I can't afford to go to the doctor right now.
