Ladies help! I’m worried on what is going on!

firstly im so sorry for the picture! i am 22 and last night i took a thrust canesten tablet+cream, i had a big allergic reaction and had swollen throat, rash everywhere almost and she was irritating even more than before. i got up the next day and feel fine but went toilet and see this in the mirror, it looks cut and white its really freaking me out as when google ( i know, worst thing to do) it says vulver cancer and everything. i also didnt notice the bump above as well. has anyone had this and can tell me? feel very anxious..! the first image ignore the two circles that was on the mirror, i also kept wiping and know its not discharge which i have been getting thick white sticky discharge.
