Prolactin Levels & Prolactin Testing. Prolactin is a hormone that plays a role in fertility by inhibiting follicle stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH), the hormones that trigger ovulation and allow eggs to develop and mature.
(The exception is a molar pregnancy, which may require that you wait six months to a year before trying again.) A study published in 2015 looked at women in four health centers around the U.S. who were trying to conceive after a pregnancy loss.
How long it takes to conceive. The majority of couples get pregnant within three months. Your own timeline could be longer if you're older, have certain fertility-unfriendly habits (like smoking), or have a condition that impairs fertility. Of all couples trying to conceive: 1  30 percent get pregnant within the first cycle (about one month). 2  59 percent get pregnant within three cycles (about three months). 3  80 percent get pregnant within six cycles (about six months).
