my maternity pictures are gonna be ruined...

I have my maternity pictures are in the morning and tonight my face decided to give me a present!!! a beautiful PIMPLE 😒 my pictures are very expensive and i don't want them ruined... I haven't had a pimple in weeks but just because I have something planned is when one wants to show up. does anyone have advice to make It go down or at least not be so red for tomorrow??
