A primary goal of this study is to assess directly the extent to which the different levels of the mucus score predict a real difference in the conception probability. In a previous analysis of these data, Dunson et al. Cycles were excluded from the analysis if there were insufficient BBT data to determine the ovulation day, if there were no reported intercourse acts during the fertile interval, or if there was a day within the fertile interval on which intercourse occurred but mucus information was missing.

Out of menstrual cycles of data with pregnancies, cycles remained in the analysis, with pregnancies. For the purposes of this study, pregnancy is defined as either an ongoing pregnancy of at least 60 days from the last menses or a clinically identified spontaneous abortion within 60 days of the last menses. Modelling and estimation of pregnancy probabilities were carried out using a Bayesian hierarchical modelling approach Dunson, This involves choosing prior distributions for unknown parameters in a statistical model based on previous information and updating this information with the data in the study to obtain posterior distributions, which represent the current state of knowledge about the unknown parameters.

In a cycle where intercourse occurred on more than one day during the fertile period, it is impossible to determine which act resulted in the pregnancy. Following Barrett and Marshall , Wilcox et al. The analyses presented in this article are based on the methods of Dunson and Stanford The significant trend was attributable to a steady increase in the pregnancy probability with each unit increase in the mucus score.

Specifically, the posterior probability of an increase in the pregnancy probability in going from a mucus score of 1 to 2 was 0.

The day of lowest fertility was 5 days before ovulation, and the day of highest fertility was 3 days before ovulation. The difference in pregnancy probability between these two days ranged from 0.

Thus the gain in pregnancy probability attributable to an increase from the lowest to highest mucus score is generally higher than the gain attributable to having intercourse 3 days before ovulation instead of 5 days before ovulation.

Within the fertile window, the type of mucus observed on the day of intercourse is more predictive of conception than the timing relative to ovulation. Figure 2 shows the distribution of the reported mucus scores according to timing within the fertile interval. On each day, type 4 mucus is the most common, with the largest proportion occurring 2 days before ovulation, which is also the day on which the smallest proportion of cycles had no vaginal discharge type 1 mucus.

It is important to note that each of the days had a substantial proportion of women in each of the mucus categories. Although fewer women reported type 2 mucus and that proportion remained essentially constant across the fertile window, there was a significant difference in the pregnancy probabilities between type 2 mucus and the other categories.

These results provide direct evidence that mucus plays a role in fertility that is more important than its previously identified role as a marker of the fertile window of the menstrual cycle. Previous estimates of pregnancy probabilities on days relative to ovulation did not account for daily observations of the quality of mucus, though researchers have identified increased conception probabilities on days when secretions were observed compared with no secretions Dunson et al.

Our study demonstrates that the quality of mucus explains most of the relationship between the pregnancy probability and the timing of intercourse relative to ovulation.

Our results have important clinical implications. Because vulvar observations of cervical mucus predict not only the fertile days of the cycle but also the probabilities of conception within the fertile interval, monitoring of mucus provides additional information not provided by other methods for identifying the fertile interval. In addition, such monitoring is expensive and inconvenient and can miss the beginning of the fertile interval and even the most fertile days.

Many women already rely on their own calculations to predict ovulation, often obtaining estimates different from results of ultrasound or LH detection Gnoth et al. Hence, monitoring of mucus provides a useful clinical marker of days with high conception probabilities. Thanks also to Allen Wilcox and Donna Baird for their insightful comments.

The LH surge is, alas, very brief — and in order to detect the LH surge, a woman needs to test at the right time of the month — and the right time of day.

As LH is produced by the body in the morning, mid-afternoon is considered the ideal time to test. Once the LH surge has been detected, successful fertilization is most likely to take place one to three days following the LH surge — with peak fertility at 36 hours post-LH surge.

Below, you will find information on getting the most out of your ovulation tests and visit our Ovulation Test FAQ for more testing tips. To determine when to start testing, you must first do a little calculating. Use the Cycle Chart below to figure out when to begin testing for your LH surge. First, determine the average length of your menstrual cycle. The length of the menstrual cycle is the number of days from the first day of menstrual bleeding to the day before bleeding begins on the next period.

Determine the usual length of the menstrual cycle over the last few months. Then, refer to the Cycle Chart to determine on which day of the menstrual cycle to begin testing. Should I be worried? As the LH surge can be sudden and over in a flash, it is possible to receive a negative result and still ovulate.

However, there are testing suggestions to help ensure the accuracy and reliability of tests. Most of these tips are covered in the bulleted points above. If you have a very irregular cycle, you may consider using an ovulation microscope which can be used for women with irregular cycles.

I would venture that if you only experience pain during sex in your mid-cycle, then your pain is most likely ovarian in nature. As the ovary is ready to ovulate it enlarges. When it enlarges it often moves down into the lower part of the pelvis. However, there are treatments that can help. Infertility can put stress on existing relationships, but implementing a few specific strategies for maintaining healthy relationships will help you….

A new study finds that epidurals do not affect child development in their later years. A fetal arrhythmia is an irregular heart rate — too fast, too slow, or otherwise outside the norm. It's often benign. Postpartum diarrhea after a C-section is normal.

Medically reviewed by Fernando Mariz, MD. Some of the most common changes include fertile vaginal discharge, cervical changes, and also your mood changes. The time period could depend from one female to the other because as mentioned earlier some females could experience EWCM for about five days and some only a day or two.

The desire for sex increases whenever the female is in her most fertile period. The hormone that is responsible for the egg white discharge is Estrogen.

This means that when your Estrogen levels are low you will not be getting quality cervical mucus. This type of situation or condition may occur due to some side effects of certain medications or due to age or some hormonal imbalance.
