Bellamine S and depression

I've now been taking Bellamine S for about a month and a half. Lately (past 3-4 days) I've been feeling tearful/depressed. Can the Bellamine be the cause? Note: I've not been drinking any alcohol or taking other medication. I'm taking the Bellamine to releave hot flashes... I'm still having the hot flashes. Question number 2, therfore is - how long do I have to be on the Bellamine before I experience releaf from the hot flashes?
