A new Cochrane review of methods to increase chances of successful conception suggests that timed intercourse using urine ovulation tests probably improves live birth and pregnancy rates in women under 40 who had been trying to conceive for less than 12 months, compared to intercourse without ovulation prediction.
I dislike the term “starting a family” which entirely discounts people who are trying to conceive a second or third child.
“conceiving” would get the point across pretty succinctly.
