Blood stain

Hi mommies. 37 weeks and 6 days pregnant. Ask ko lang, if sign na ba to na lalabas na si baby? Worried kasi ako kasi may blood na sa undie ko but still no contractions. How long does it take po kaya before maramdamang ang contractions? Any advice po? Thankyou! Ps. Excuse my undie kung butas hahahaha di ko din alam bat nabutas yan eh bago palang naman hahaha. Siguro dahil ng discharge and acidic. #1stimemom #pregnancy
