HELP MY FACE IS RED

So I exfoliated and cleansed my face and apparently your not supposed to do both but I thought I usually did. I took them both off quickly with cold water like always. And after an hour red patches appear on my face when I'm doing my skincare. I was putting on a serum that I've used before and it doesn't make my face red so I was like it's not that. And then I look in the mirror again and my whole face is bright red, its redder in person. I've put a lot of moisturiser on since then to keep it moisturized. But I dont know what to do. How long till it goes away? Is my skin going to be okay?? I need to leave the house in an hour and I'm on my period so I might just burst into tears. This has happened before but I dont remember what I did and it's never been as red. HELP
