Unfortunately, law schools look at the LSAC-calculated GPA, which includes all classes you took before obtaining your BA. Do you know what that GPA would be? The good news is you have a strong LSAT score, so you should still have a shot at some good schools. There are a lot more people with great grades and mediocre LSAT scores than the other way around, so that helps you.
Law school admissions is primarily a numbers game. But if you have a good addendum and an upward grade trajectory, I think that can help. Getting some work experience and even more distance from the bad semester might not be the worst idea either.
