Question about supply and latch!!

Dylane • Mommy of both.💙💜 Married to my best friend.🧡

This is going to be long so if you read it, thank you!! If you can help I would appreciate it so much!

I had my daughter on February 24 around 9am, well she slept basically the whole first day of her life after the first feeding when she was born, and stayed attached to me pretty much all night. Then we left early the next morning. When we got home I continued trying to breastfeed but she constantly acted like she was hungry, so on Wednesday February 28th I gave her a bottle and started supplementing and I got to see a IBCLC on Friday. She helped with her latch but I still had to supplement because she'd lost a lot of weight, and I had to use formula because I didn't have a pump. On Saturday I took her to the hospital because I couldn't get her to wake up to eat and she was yellow. They tested her bilirubin level and it was 14.8 at 1 week old and she was still 6oz down from her birth weight. I was super worried about not getting her to gain the right amount of weight so I just started giving her formula so I knew exactly how much she was getting so I could tell her doctor. On the next Monday at her pediatrician she was much better and her jaundice was almost gone but she was the same weight as Saturday. On tuesday we saw the IBCLC again but my daughter was either not hungry or was just being lazy because she'd gotten used to the bottle so that got me down and I kind of gave up after more failed attempts at home. I got a Manuel pump and tried to pump for a few days but stopped around March 10th because I just got really upset about it. But now she's 1lb over her birth weight and I was hoping I could somehow get her to relatch and be able to breastfeed. I have a double pump now and have been trying to pump but I'm literally only getting drops and I'm bleeding and it hurts so bad. I'm wondering if it's possible to get my supply back, how long will it hurt like this, and is it possible to get her to relatch and be able to breastfeed? I’m drinking plenty of water and eating, and pumping every 2 hours, and still nothing.
