These dates are rarely the same

Dating pregnancy with irregular periods

However, it can be a daunting task to determine your due date, especially if you have irregular menstrual cycles. The calculation of the due date from this symptom, however, depends on if you have regular or irregular menstrual cycles.

Here I explain

In the first few weeks, fetuses tend to develop at the same rate. Pregnancies are conventionally dated in weeks, starting from the first day of the last menstrual period. To make this task easier, you might consider using an electronic fertility monitor like the OvaCue.

When a doctor performs an ultrasound, they write a report on the findings and include two estimated due dates. However, if the date of the last menstrual period was accurate, an allowance of a week before or after the due date is considered fairly accurate. Ultrasound measurements for estimating the age of a fetus are more accurate during the early stages of pregnancy. We follow the same process in the third trimester, with a three-week difference.

The pregnancy wheel This is a prepared wheel that matches the dates of your last menstrual period with a due date. The date of the last menstrual period can be determined as earlier explained. Results may be available in about half an hour. Avoid numerous scans and have ultrasounds for medical reasons only. Your doctor may change your due date based on the ultrasound measurement.

The second date is based

Laboratory pregnancy tests Doctors test a sample of urine or sometimes blood from the woman to determine whether she is pregnant. In addition, the herb Vitex agnus-castus commonly known as Chasteberry has been shown to help promote hormonal balance, restore cycle regularity, and increase ovulation frequency.

Ultrasound dating is based on a series of measurements of the gestational sac in very early pregnancies and of the embryo or fetus itself as pregnancy progresses. Human chorionic gonadotropin is a hormone produced by the placenta early in pregnancy. These symptoms include morning sickness, putting on weight, cravings and food aversions among others.

Here I explain the three methods of pregnancy dating and how medical professionals use them. The second date is based on the ultrasound measurements. If results are negative but the woman still suspects she is pregnant, she should repeat the home pregnancy test a few days later. The chances of actually having your baby on that exact date are very slim. Pregnancy wheel The other way to calculate your due date is to use a pregnancy wheel.

For women with irregular periods, ovulation prediction can be a frustrating endeavor. Although they may not be totally accurate, these methods help a great deal in having a rough due date in mind. Understanding the causes of irregular periods and how you can help to restore cycle regularity can help as you embark on your trying to conceive adventure. This method continues in the subsequent trimesters.
