There's something wrong with my game.

[mreinecker]

I play quite often with a group of people at my house or one of theirs. The games are usually 5-8 man games with 5 dollar buy ins. Anyway, I keep a log of my winnings and losses. About up until a month ago, I've been pretty much even. I win some games, and I lost some. But, lately my game has turned around. I can't seem to win a game. I don't seem to catch ANY good hole cards worth playing with either. Our games are usually pretty loose. I've been playing more on the tight side lately, due to the fact that I'm not getting many good starting hands. However, even when I do catch some overcards, I'm usually beat on the flop or on the turn. I don't know what to do with how I play. Should I have a certian strategy ? Please help me out.
