That's rough. It's a weird statistic, and I would not quote it to the unfortunate parents, but when you miscarry it actually increases your chances of a successful pregnancy in the future. Kinda like a practice run for her ovaries, if that's not too insensitive an analogy.
I thought miscarrying increased your chances of miscarrying?
Only if you get pregnant again right away. If you wait a few months your cervix is more open (or her cervix, as the case may be) and your body is less likely to reject the egg. At least, that is what I heard. I'm no doctor, of course, so everything I just wrote could be total BS.
I am pretty sure that miscarrying increases your chances of miscarrying again.
This is for % chance of miscarriage.
First pregnancy 5%
Last pregnancy terminated 6%
Last pregnancy a live birth 5%
All pregnancies live births 4%
