Pimples

So I am okay birth control and started a new brand about three months ago. I’m usually only ever get break outs right before my period but once I was on birth control it wasn’t as bad. Ever since I started the new brand though, I have tiny blemishes on my forehead that never break the skin. They are just bumps. It freaked me out at first cus I thought maybe I was pregnant and this was a symptom but I took several tests and this has been going on for about a month now. It’s not bad enough that I even need makeup to cover it up but if you look close enough you can see them. Could this be from my birth control?
