Uy, that's a really important question about your cervix after the cerclage removal, definitely something you need to ask your OB about directly, ha! Every pregnancy is different, at 37 weeks na kayo, so your doctor needs to check exactly what's happening with your cervix at your next visit or even sooner if you're worried. A few of us mum friends na nag-undergo ng cerclage, ang experience namin ay different, some had the cervix open right away, some took time pa, pero yan talaga dapat i-monitor ng doctor mo closely ngayon. Wala akong makukuhang answer dito na safe para sa inyo, but your OB will know exactly what to look for. Go see them ASAP kung may concerns ka, okay?
