breastfeeding help, losing hope..

Yenifer
Day 3, My milk doesn't want to come in 😩. I had to start giving formula because my nipples cracked and bleed. My daughter has a strong suckle and I started getting poop for it because I'm starving her and she gets fussy. Giving formula she drinks 2 oz every 3 hours! Was I depriving her from food? How awful! I started pumping but I get a drop of colostrum a day, it's so embarrassing.Â
