Uy, totally normal yan po! Kaya nag-improve na ng slightly ang greenish discharge mo, ang milky white is usually just your vaginal wall healing and shedding off the old cells after the infection, ganun talaga after antibiotics or metro gel. Some mums I know said it took them a good week or two pa rin after finishing meds para mag-settle completely, pero as long as it's not foul-smelling or super thick and clumpy, you're on the right track. Good call na makikita mo pa rin ang OB today kasi sure, but honestly this sounds like your body doing its job na mag-recover, don't stress too much about it!
