My female PC (a fighter/paladin) has had two children, and adventured during both pregnancies (she kept the suit of "maternity full plate" for sentimental reasons). The DM and I had an agreement that, if she had been dropped to 0 hp or less, there was a very good chance she'd miscarry, but the missions were important enough that my PC really didn't think twice about it.
Both pregnancies were more-or-less planned (the PC is married). The campaign's been going on for 25+ years; the "mom" PC is semi-retired now, and her older daughter is now one of my PCs, as well.
All of that said...as a male player, I probably have no clue about the emotional impact of a pregnancy (especially an "unplanned" one) for a female player.
