Don't sweat it too much. You are probably right and the new birth control is most likely the cause of your breakout. I had a similar experience when I started on a new pill. Anyway, just stick it out because I found that after the "initial" breakout goes away, I haven't broken out on my chin for awhile now. Consider yourself very lucky that you don't break out along the jawline or anywhere else.

Good to hear other people have gone through the same thing! I think so too, my chin has healed nicely and I haven't broken out since so hopefully my skin will have some time to calm down before/if I breakout again. Thanks
