OB prescribed combination BCP while breastfeeding

Do any of you postpartum mamas have experience with this? I know about the potential to decrease my supply and I mentioned it to my OB but he said as long as my milk supply is well established it shouldn't be a problem. But of course I've been googling and freaking myself out. Anyone else's OB prescribe combo pills? How did it work out for you? My doc was really pushing the IUD which I don't want, so I wonder about his extent of knowledge with pills. Thinking about calling and requesting another doc at the practice to see what they think.
