Need breastfeeding help

My LO is 6 weeks old and have been EBF since 2 weeks due to latching issues. the past week she has been getting irritated on while feeding squirming around and using her arms to pop off, even though she doesn’t want too and immediately is looking to relatch. I’ve tried burping when she seems uncomfortable but it doesn’t seem to do anything! i’ve tried gripe water and gas drops but still having this issue. her latch seems to be good and i know i have milk in there. any tips or ideas of what might be going on?
