drying up 😢😪

Mercy • I'm 27 years old and me and my husband are expecting our 2nd baby in March. Our daughter is almost 2 and we are excited to be giving her a sibling!
For those mommies out there that have dried up. Did it hurt? What did it feel like? I feel like I'm being punched in the boob. I sometimes only get one ounce from both breasts after pumping and baby sometimes seems fairly hungry after nursing. I'm currently starting to feel a lot of pain mainly in my left breast could I be drying up?Â
