I started my depo shots April 2016. I had bleed for one week in May. Bleed one week stoped for a few days then started bleeding again in June. The, the bleeding stopped for a few days and started again and I bleed for another week in July. And then had not had a period since. Now it's December and I've started spotting. I don't know why This is happening or what to do? Had this happened to anyone else?
