It can cause the endometrium to not support a pregnancy
learn about Prolactin at http://www.conceivingconcepts.com/learning/articles/prolactin.html Hi...you will have a better picture on this issue with the below. Hyperprolactinemia does not directly cause miscarriage. However, Hyperprolactinemia may contribute to luteal phase defect. The luteal phase is a part of the menstrual cycle. It is the time between ovulation and the start of the next period. Most of the time, the luteal phase lasts for between 10 and 14 days. If your luteal phase lasts less than 10 or more than 14 days, it is referred to as a luteal phase defect. If you conceive and you have a luteal phase defect, you may an early miscarriage. This is because that a luteal phase defect cannot sustain a pregnancy because the uterine lining in these women begins to break down, bringing on the menstrual bleeding and causing an early miscarriage. http://www.amazingpregnancy.com/pregnancy-articles/441.html
Luteal phase
Menstral Cycle
Women have their luteal phase soon after ovulation is finished up to their first menstrual period. On average, women have a 14 days luteal phase. The normal luteal phase is 10-16 days. But if you want to get pregnant having 12 or higher luteal phase is ideal.
The luteal phase begins after ovulation and is characterized by the presence of the hormone progesterone. It typically starts around 14 days before your next menstrual period, following the release of an egg from the ovary. The luteal phase ends when menstruation begins, signaling that pregnancy has not occurred. Tracking your menstrual cycle and ovulation can help you determine the timing of your luteal phase.
follicular phase, ovulation, luteal phase, menstruation
The luteal phase typically remains relatively consistent in length, around 10-14 days, due to the influence of progesterone released from the collapsed follicle after ovulation. However, variations in the length of the luteal phase can occur due to hormonal imbalances, stress, changes in diet or exercise, and underlying health conditions. Tracking your menstrual cycle can help identify any changes in the length of your luteal phase.
The second phase of the menstrual cycle is called the luteal phase. It begins after ovulation and ends just before the start of the next period. During this phase, the uterine lining thickens in preparation for a possible pregnancy.
From doing research it is possible to have LPD after a normal pregnancy, from reading nothing indicates that pregnancy itself will/would lead to this problem but I suggest doing some research maybe on FertilityFriend or one of the other fertility web sites to get more information. Basically having a normal pregnancy once does not necessarily mean you cannot have fertility issues later. Anything is possible. I had a Luteal Phase Deficiency for years which was the cause of my infertility. There are progrestrone supplements ie Duphaston, Crinone that can assist the phase however, they are prescribed by your doctor.
To calculate your luteal phase, first track your menstrual cycle for several months to identify the length of your entire cycle. The luteal phase typically lasts about 14 days, starting after ovulation and ending when your period begins. To determine the luteal phase length, subtract the day of ovulation from the first day of your next period. Ovulation can be estimated using methods such as tracking basal body temperature or monitoring changes in cervical mucus.
