Home remedies for a UTI???

So I believe I have a UTI. My boyfriend and I have sex a lot and he's not very gentle. Recently I have had the constant feeling of a full bladder and only peeing a little. Also now when I'm toward the end of peeing it's a feeling I can't explain but it's painful. Not horrible but not normal. I believe this is a UTI and I wanted home remedies. Any advice or tips would be appreciated
