Ay, that's exciting na, mama! Hindi necessarily agad agad, nakita ko sa few of my mum friends na nag-lose ng mucus plug weeks pa bago mag-labor, kaya basta monitor mo lang kung may cramping or spotting after, at best na i-update ang OB mo during your next checkup or kahit ngayon kung worried ka. Good luck, at fingers crossed na malapit na talaga!
