The answer to this question is that we don't know for sure, because there aren't enough records to tell exactly what the population average was.

However, what we *can* tell you, from a primary source of the extensive diaries of Martha Ballard, a midwife in rural Maine between 1785 and 1812, among her patients 38% of them had conceived before getting married.

Born in 1735, Martha Ballard kept a daily diary covering her life, her work, and the weather in the Massachusetts frontier in present-day Maine. The diary spans 27 years and has over 1400 pages. From this rich data, lots of things can be inferred, such as that people on the frontiers did a lot of fucking in the early summer, because there were seasonal spikes of births in February-April.
