Mama, please go back to the hospital or call your OB right away, bleeding with regular contractions even at 1cm needs to be checked immediately, hindi ito normal at hindi dapat palampasin.
I know it's scary, but you're doing the right thing by being alert. Maraming cases ng bleeding in early labor, pero kailangan talaga ng doctor para makita kung ano ang nangyayari at ma-monitor ang baby. Wag mag-atubili bumalik, better safe than sorry, lalo na with contractions every 5-8 mins pa. Hoping everything's okay with you and baby.
