Im breastfeeding and have pcos, IMPLANON or DEPO?

Hi, my baby is about 10 wks or so and I want to get on bc as I have a 22mo old and a 2mo old...dont want any surprises. I am breastfeeding and plan to until she is 12mo, and I also have pcos. When I went to my 8 wk check up the gyn was being fairly rude and careless i told her i needed bc and i breastfeeding and she gave me ortho-tri-lo I know if i took that my milk would dry up so i didnt take it. well i want to choose between IMPLANON OR DEPO SHOT ive never been on bc and im married so condoms are out. Ive read scary review between the two WHICH WOULD YAL RECOMMEND FROM *EXPERIENCE*..? thanks ladies
