We have another baby on the way and I was thinking about asking this previously, but wasn't sure how common it was as our first child predates this site by about 4 years.
Now we have another on the way it has come up again and people keep telling us we shouldn't be announcing our pregnancy until the second trimester.
Their suggestion is that it is more likely that there will be complications in the first semester and this will ultimately lead to our embarrassment. This is usually mentioned quite abruptly as if this a regular occurrence and we will suffer the consequence of going around telling everyone.
Based on fact, in the developed world do more deaths happen during the first trimester or during the rest of the pregnancy including labor?
This would be for a healthy female aged 18 - 35.
I also don't know if this has any effect on the figures, but it should be assumed that during the first trimester a pregnancy is not identified until after 5 - 6 weeks has already passed. As nobody would go around announcing something that never happened if there was some sort of complication during that period.
