INFLAMED LABIA!!! HELP

someone please tell me what i should do, my labia is EXTREMLY SWOLLEN. it happened last night and it’s still the same this morning, i’m freaking out and my obgyn doesn’t have an appointment until Wednesday. it happened right after sex, i don’t think it’s an allergic reaction because we don’t use condoms (iud) and i’ve had the same partner for over a year. all we use is a little bit of coconut oil. please help i’m really freaking out, they won’t even fit in the labia majoria which is not normal for me , they look like inflated balloons
