Mama, please go to your OB or emergency room right now, light bleeding with an open cervix at 27 weeks needs checking immediately, hindi pwedeng palampasin. Your doctor needs to see you today para ma-assess kung okay ang baby at kung kailangan mo ng extra care, lalo na may gamot ka nang na-prescribe. Don't worry about bothering them, ito na talaga ang oras na kailangan mo sila. Sending you strength, mama!
