Bump and pressure on forehead after Botox?

I got Botox for the first time about a month and a half ago. I've recently noticed that if I apply too much pressure to my forehead (resting my hand on my forehead, taking off makeup, squeezing my eyebrows together), I can see the Botox clump into a bump on my forehead.

Typically, this happens between my eyebrows. The bump will stay for about a minute, then relax and smooth out again. Also when this happens I get an intense pressure on my forehead. Is this normal? Is something wrong?
