They say 10 weeks, at the doctors office, when they hear the heart beat, and do a transvaginal ultrasound and see the baby, then the chances are less for miscarriage after that point. Hope this helps. (:
One more week in you'll be in your second trimester that when chances of miscarriage decrease drastically! But if you're this far along and having no issues you should be fine!
its either 12 or 13 weeks.....they say the chances go down after 3 months.
