Hello, I am having light brown clumpy period blood for the first two days then it turns regular for the rest of my period. Is this normal?

Yes it's normal. But then if there's any unusual symptoms like pelvic pain, prolonged menses with clots, then i'd recommend u follow up with ur gyn for further exam. God bless u! http://m.Healthline.Com/symptom/menstrual-irregularity.
