Yeah. Keep lifting as you have. If you cannot see abs, then your body fat has not dropped especially low such that some major alteration is mandated. Just keep going. Maybe one week off might help matters. It often does in these circumstances.
Next: ditch the refeeds. I used to recommend these obsessively, but after much thought I began to feel that they were being misused and abused. The purpose of structured refeeds, really, is supposed to be restoring diminished glycogen stores which in turn is supposed to help restore normal hormone function (levels of leptin, ghrelin, thyroid) - this in turn has positive effects on appetite control, mood etc and thus makes dietary adherence easier. The refilled glycogen stores, additionally, will help with working out. This all sounds well and good, except that it seems unlikely that one big refeed every 2-3 weeks or so is going to have a great effect in the grand scheme of things. Add to that that at higher body fat levels the adverse effects of diet on hormonal function and even on exercise are just going to be less.
I like tactical refeeds, but think they are better in people with very low body fat and done on a frequent basis, even as often as a few times a week (hence good for people trying to lose that last bit of fat slowly rather than rapidly). I don't think the refeed has an enormous amount of benefit for you, and indeed is more likely to slow you down from reaching your targets. In sum, my opinion is that the physiological advantages of the refeed are too insignificant in your case for it to be warranted or recommended.
Plan some cheat meals instead. The odd one here and there, once a week or whatever, won't do much harm (unless you go psycho at an eat-all-you-can buffet) and will help psychologically.
