Good day i'm not sure if i have a problem or not but i'm struggling with getting a child?

Question unclear but: Generally, a guy can meet someone nice, date a while, get engaged, get married, relax, start having sex once or twice a day during wife's fertile days, and hopefully get pregnant soon. The fertile days are about days 10-15 in a 28-day cycle. Of course, if a couple has sex every one or two days throughout the month, no need to think about fertile days.
