my girly parts are confused- any advice would be awesome

Nicole

alright, so from the beginning. My mom put me on birth control at 13 using the depo-provera shot I use that for about 3 years and then went to the pill. I tried the Implanon and I tried a copper IUD neither which quite work with my body. I am on the pill currently. I had about two periods between 13 and 15, and then two periods after I turned 18. About a month and a half ago my dog had eaten my birth control pills and I went without it for an entire month now at this point I have bled twice since October 29th for a few days. it's not a heavy flow by any means but I'm just kind of trying to figure out what's going on. My boyfriend and I do plan to have kids in the future so I'm trying to regulate things but I guess I don't really know how it works. in addition I was diagnosed with PCOS when I was 14 I'm not sure if that's relevant. let me know your thoughts on my weird body.
