Yeast infection - Monistat 1.

Hey everyone. I ended up with my first yeast infection. I know they are normal. My boyfriend works second shift & I woke up to two bottles of water & a box of Monistat 1. I just inserted the ovule about 4 hours ago. Does it break apart & come out or what? I'm not sure what to expect from this & I don't want something that should happen to scare me. Who has used it before?
