Uy, mama, this sounds uncomfortable talaga, please check with your OB or a lactation consultant right away, ha, especially with the dugo. Hindi ito something to figure out on your own.
In the meantime, a few of us mums swear by Mama's Choice Nipple Cream para sa soreness at cracking, it's pregnancy-safe at breastfeeding-safe, kaya okay gamitin habang nag-latch pa rin si baby. But talaga, kailangan mo ng professional check-up muna para malaman kung ano exactly ang problema, whether it's just cracking or may ibang issue. Sending you a hug, first-time breastfeeding can be tough!
