Sis, normal lang ang kaunting dugo after IE (internal exam), nangyayari yan dahil sensitive ang cervix especially pag approaching labor, pero hindi yan automatic sign na fully open na ang cervix! A few of us first-timers din nag-alala nyan, pero the doctor should've told you exactly kung ilang cm na kayo or kung "favorable" na ang cervix, that's important info you deserve to know, kaya don't hesitate to text or call your OB para clarify, okay? Better safe than sorry, lalo na first time mom ka pa lang.
