Aw, yan talaga ang nakakatakot ng first IE lalo na pag may blood after! But yes, normal lang yan, the cervix is super sensitive ngayon kaya madaling mag-bleed a little during internal exams, hindi always mucus plug. Kung small amount of blood lang and no cramping, wala masyado alalahanin, pero definitely mention it ulit sa next check-up para peace of mind mo. As for how many weeks bago umakyat ang dilation, honestly it varies, a few of us moms had 1 cm for weeks, some jumped to 3-4 cm in a few days lang, so unpredictable talaga. Regarding evening primrose, walang nakakatulog siya talaga, it's meant to help soften the cervix, hindi para sa tulog, pero if you're taking it, best to confirm with your OB muna kung okay for your situation. Honestly with the bleeding and questions mo, good idea na mag-follow up with your doctor just to be sure everything's good with baby and you.
