how many months do half-trimmed eyebrows take to grow?

I had trimmed the inner edges of my brows a month back. And many said that it would take just a few weeks for them to fully grow. But can't see much or any change. Please frankly tell me as to how many more months will I have to wait? It's driving me crazy. It's just half trimmed, half of it still there. No roots yanked out and nothing of that sort. So, how long?
