When using any kind of vaginal progesterone gel to apply, it’s normal to leak out. As long as you keep on applying it, the excess will leak out. This doesn’t mean the gel isn’t used correctly or isn’t being absorbed completely. The excess comes out, and even the excess build-up should also be removed from time to time. You can use panty liners whenever you apply a progesterone gel to ensure you don’t ruin your clothes.
