Having AC trouble after charging it.

About 3 weeks ago I charged my car’s AC. It my first time doing it and I think I messed up pretty bad. While charging the AC I noticed nothing happened when I pulled the trigger to the Freon bottle. So me in my infinite wisdom turned the bottle upside down thinking something would happen. And something did happen, it worked. The gauge went from 23 to 38 so I decided to do it again so it’d be at the higher end on what the bottle said was good. But after doing it again the gauge read it was in the red but the reading fluctuated from the red to the green and I thought it was all done. But a day later driving to work I noticed my car blew hot, humid air that would fluctuate from hot air to cool still humid air, about 5 minutes before it’d switch to from hot to cold and vice versa. After about a week of this I texted my Grandpa who’s well versed when it comes to cars and he said my AC blower was busted but I don’t think so because my car still blows air but now hot, humid air. After researching online I think I may have flooded my compressor. Any ideas on what might be broken?
