Newborn throwing up

Help please!!!! My newborn is 3weeks and 3 days old and for the most part she’s done well with feedings. However, since yesterday I’ll feed her and everytime i burp her throughout her feeding she’ll throw up what looks to be like most of what she ate. I typically burp her every half ounce or less and she’ll typically drink 2.5-3 ounces per feeding every 2-3 hours. I’ll burp her and she’ll let out either a small or large burp, be fine for about 10-15 seconds then throw up most of what she ate. Anyone have any tips or know what I can do to help? She’ll also still want more food after throwing it up but I feel bad feeding it to her for her to just throw it up.
