mucus plug

Hi, I'm at 36 weeks and 4 days. I went for prenatal check up kahapon ang my ob said 1cm dilated na ako, kagabi nag discharge ako ng makapal na maroon pagkatapos sinundan ng puti na may mga red streaks, yun na yata mucus plug ko. Gano po katagal mag start active labor after that? Sbi ng ob ko term na din dw si baby in a few days so ok na at pwede na manganak anytime. Edd ko po is July 4. Thanks!
