You will always face periods where results don't go your way. Most people get them at least once per season. I know I do. I find I often have a disappointing result in the league just before a crunch match...could be you just had the same.

If you post some details about your team on here, people can give you advice...to be honest, without knowing more about your team/opponents, any advice you get is just as likely to make things worse than help you.
