So I am new to brewing and started my first brew last week. It has been 5 days since I added the yeast to let it ferment. I am using a bucket and my airlock has not had any action. I pressed down lightly on the lid and it bubbled then. I also couldn't take it and opened it up and looked inside. It is foaming up and looks great and smells wonderful. But it worried me a little that the only time it has bubbled is when I seemed to have forced it. The temp has stayed pretty constant. I was wondering if everything seems to be fine and it might be just a small air leak and I could leave it alone to Finish fermenting or if it could be something worse?
