While some couples make a baby the first time they have sex (whether they want one or not), other couples may try for months -- or even years -- without getting the child they want so badly. Some women need to know more about how to get pregnant if they are having trouble conceiving. In order for pregnancy to occur, a couple has to have intercourse during the woman's ovulation and fertile "window." But because the time of ovulation can be hard to determine, a couple that wants to be pregnant should just make sure to engage in unprotected intercourse at least two or three times over the course of each week, without worrying about "perfect timing." If a woman hasn't conceived within a year or so of regular intercourse, she should talk with her healthcare provider.
