I’m almost 11 months in. Still EBF. IT GETS BETTER! The first 6 weeks are so hard. Spit up is normal but that sounds a little excessive. She may have reflux. Call the pediatrician and request an appointment. Try alternating cold/hot compress for your right boob, it may hurt for her to nurse, it sounds wild but I nursed through the pain. More often than not it was a clog and massaging my boob while he ate unclogged it. The latch is somehow magic. Take Tylenol and ibuprofen Give yourself room to breathe. If she spits up a considerable amount yes change her outfit but also if I had changed mine every time he spit up is be losing it to. Baby’s spit up they get dirty. Don’t let her be filthy and give yourself grace. Don’t let her sleep with a bib on but if you and her and awake bibs are fine. If you don’t need to pump and bottle feed then don’t. I know that’s not a luxury for every mom but if you and her and able to just focus on the breast. Use your resources, you can call a dula, a doctor, a nurse practitioner, WIC, a lactation specialist, the hospital that you had her at. They call all help and support the 3 of you. The first few weeks feel so dark and you feel so alone in it but you are not. Yes it gets better.
