Spot pops after wudu

Salam, I have acne on my face and after doing wudu some spots burst. Today I was doing wudu and when drying I avoided the spot but it burst and I wasn’t sure whether my wudu was valid so I waited and wiped away the pus and blood. After that another one burst whilst doing wudu and I got fed up so I tried washing out the blood and only a very small amount was on the surface of it but it was dripping down. Is my wudu valid?
