Thin and tissue paper like vaginal discharge

Anyone who experience this kind of discharge. Nakuha ko po ung discharge na to nung pinasok ko sa loon ung daliri ko and I saw that kind of discharge. Ano po kaya ibig sabihin niyan? 4 days before my period po nagkaroon ako ng ganyan discharge. Normal discharge lang po ba yan na malapit na ko reglahin? Or early sign of pregnancy or sign of ovulation? PS: Hindi po siya stretchy and clear para siyang tissue paper na pag binasa mo.
