First time mom breastfeeding...

Katiana.
My baby is two weeks old and I am doing everything backwards! First my baby wasn't latching. Then I went to see a lactation consultant and we were able to get an ounce out of her from each boob. The first 3 days I was pumping 2-3oz in 20-30 minutes. Then it decreased after a week to 1 oz or less! At this point I did not know what to do! So I had to give in and give her formula. Per doctor she was worried for a few days old I was not feeding her as I was suppose to. I wasn't against formula. But my goal was to breastfeed. Now, I'm eating!! Smh and drinking lots of fluids. My supply is coming back slowly. So I am back and form with pumping during the day and formula at night. Also, I've been trying to get her back on the boob then take the bottle. Am I wrong for doing this? I'm all over the place! Also, my left boob is a lot smaller than the right! How can I get her to like the left and latch on to it???
