Past 5 days I am having whitish and brownish discharge. Sometimes on and off. From 31st to 33rd day I had whitish discharge with a dot of brown discharge in very lesser amount but in last two days I am having brown discharge that too again in lesser amount only. Still now no periods. What might the cause be??? Is this any medical condition??? Or is there any chance of me being pregnent but I feel no symptom of pregnency...
