Sabar dulu, since you just habis makan antibiotics for the infection, it's normal untuk ada spotting atau discharge yang berubah warna dalam few days to a week or two after treatment, especially kalau mmg ada infection before. The fact that baby is active and you're not in pain is a good sign! But honestly, dengan history of infection ni, better text your doc or clinic nurse just to confirm everything's settled properly, tak payah tunggu next checkup, they usually respond pretty fast je. A few of my mum friends went through similar and their doctors just said to monitor, but peace of mind tu priceless kan, especially first pregnancy
