Baby cries after feeding....help!

Blessedinlove

For two weeks straight my LO was nursing great. She was happy and content and things were going well. For the past 3 days..she SCREAMS about one minute after each feeding and will scream for a while....seems like she is in pain. It is so sad. I am at a loss.  I keep praying it will stop since it was going so well for two weeks. I dont want to fail at breast feeding but It is killing me to see my little one so unhappy. Her feedings are fairly short and frequent.  I have lots of milk..I know she cant still be hungry as milk is still coming out when she stops. ANY help or advice or thoughts would be appreciated. I am so scared of not succeeding at this.
