DA - Also, I'm pretty sure by the time she goes back (back to Jamie's time, I mean, not back to her own time) she's menopausal. They very much don't make the character look that old, but yeah, she is in fact late forties.

I mean, I still wouldn't be in a hurry to swap the relative comfort and safety of the mid-twentieth century for the fuck-all of the 1700's.

Just saying, specifically re: the birth control/childbirth situation, it probably wasn't a concern for her by the time she went back.
