It seems to be asking for trouble, if the seal weakened during childbirth, they should only have men become jinchūriki to avoid the problem entirely. Considering that most jinchuriki were treated as weapons and tools, i don't think many jinchuriki got friends,let alone wives or husbands.

Konoha seemed to be the only nation to actually use it's jinchuriki as a jailor, married to the Hokage. So the only nation it would ever be a problem is the fire country, and even then it would happen in a highly predictable fashion that can easily be averted.

So long story short, it's unlikely to be a problem and even when it occurred, it rarely was a problem.
