Hi mama, ang admits tip ay usually nangyayari within 24-48 hours before labor, pero talagang iba-iba sa bawat mom, some nag-experience ng longer, some mas mabilis lang, kaya hard to predict talaga! Best to discuss with your OB kung anong signs to watch out for at kung kailan na talaga dapat ka mag-head to the hospital, kasi sila ang makakaalam best based sa your pregnancy. You're doing great preparing for baby's arrival, and soon na yan, you've got this, mama!
