Any moms ever breastfed and been on birth control patch?

I’m expecting my third child and I have always breastfed my children and given them formula as well. This time around I want to just breastfeed but I’m concerned about not producing enough milk. I’ve been doing tons of research because we certainly do not want baby number 4 to be brought about before a 3 year mark and I’ve read that some birth control may affect your milk production. I had really bad side effects on the depo shot. & am definitely scared about getting an IUD. So considering the patch but I do not want it to affect my milk supply. Help!
