I've had 6 game out of the money streaks. Don't concern yourself with them unless you feel that it means you are making a mistake or missing something in your strategy.
A few weeks ago, I wasn't hitting anything and realised my game plan needed revising. Since then, I'm back in the money consistantly.
Suckouts happen, play at a low enough level (to your bankroll) that you can hit a 6 game suckout fest and have it not bother you.
When you play with a good BR technique, you just shrug it off to variance.
If the suckouts hurt, consider dropping back.
3 game winning streaks are also a part of variance and they feel great!!!
