38weeks and 2 days ... No signs of labor

Exactly on my 39th week, nagstart na ko mag-labor but weeks prior to that 37-38 wala akong kahit anong signs. I didn’t even feel na nag “drop” ang baby. Kasi mataas pa yung tummy ko talaga so inexpect ko na baka abutin pa ko a week before christmas. Lumabas lang signs na manganganak na ko HOURS before the birth of my son. 5 hours na labor. Sometimes ganon daw po talaga lalabas lang mga signs the day na manganganak ka na.
