Now that a number of states have handed payments that successfully ban abortion after a fetal heartbeat may be detected, the brand new legal guidelines are elevating a whole lot of questions on early being pregnant and miscarriage therapies.
The fetal heartbeat can sometimes be seen on an ultrasound at round six weeks into being pregnant, however many ladies don’t know they’re pregnant at the moment. So when do girls sometimes notice that they’re pregnant? And how usually are pregnancies unplanned? We’ll clarify all of this and extra.
How is the size of being pregnant measured?
It sounds odd, however docs measure the start of a being pregnant as being the primary day of your final interval. Why? They’re monitoring the size of being pregnant utilizing a virtually 200-year-old calculation known as Naegele’s Rule, named after Franz Karl Naegele, the German obstetrician who’s credited with creating it within the 1800s.
Here’s the way it works: To determine when a lady will give beginning, docs begin with the primary day of the girl’s final menstrual interval, rely again three calendar months after which add one yr and 7 days to that date.
The rule is considerably complicated, as a result of conception normally doesn’t happen till round 14 days after the primary day of your interval, assuming you will have a 28-day cycle (which many ladies don’t for a variety of reasons). The reason doctors still use the last menstrual cycle as a benchmark is because it is difficult to know exactly when the sperm fertilized the egg.
So when doctors say a woman is six weeks pregnant, it typically means the embryo started developing about four weeks ago.
The heart, which can be seen flickering on an ultrasound, is still maturing and cannot be heard until several weeks later.
Perhaps this is the simplest way to say it: Six weeks pregnant is two weeks after a woman misses her period.
What does the latest abortion legislation mean for women with unviable pregnancies?
Georgia, Kentucky, Mississippi and Ohio have this year passed so-called heartbeat bills, which effectively prohibit abortion after six weeks, and other states are poised to follow in their footsteps.
Most notably, Alabama’s governor recently signed into law the nation’s most restrictive abortion bill, which bans abortions at every stage of pregnancy and criminalizes the procedure for doctors.
According to the American College of Obstetricians and Gynecologists, one of the biggest concerns of their members right now is about how to interpret the scope and application of these laws in their practice. In some instances, that extends beyond the delivery of abortion care to questions about miscarriage treatments like dilation and curettage, which removes tissue from inside of the uterus.
Women are also wondering how miscarriage will be interpreted under the law. But it’s not entirely clear because of the way the laws are written.
For now, abortion is still legal because these laws have not yet taken effect. In addition, the legislation is expected to be challenged in court because of the precedent set by the 1973 Roe v. Wade Supreme Court decision, which says abortion is legal until the fetus reaches viability, usually at 24 weeks.
When do women first learn that they are pregnant?
While there isn’t clear data as to when women typically find out that they are pregnant, Dr. Dana R. Gossett, the vice chair of obstetrics and gynecology at the University of California, San Francisco, said that in her practice she often sees women who don’t realize they are pregnant until after the six-week mark.
“Typically, clinical symptoms like fatigue and nausea don’t start until after six weeks,” Dr. Gossett said, though there are some women who are more sensitive to early pregnancy symptoms.
What’s more, women with irregular menstrual cycles might find it “especially challenging” to discover that they’re pregnant right away, Dr. Gossett said. “What are they supposed to do? Check pregnancy tests every four or five weeks?”
Dr. Sarah Horvath, a family planning fellow at the American College of Obstetricians and Gynecologists, agreed.
“Unless a woman is actively trying to get pregnant, she is unlikely to know that she is pregnant at six weeks,” she said.
Nikki Young, 42, who lives in Riverview, Fla., said she and her husband were surprised to discover eight years ago that she was pregnant.
“It was mixed feelings,” she said.
At the time, their second child was only about 1-year-old and she wasn’t actively monitoring her period.
“I didn’t really keep track of it that closely,” she recalled. But then, one day she noticed she was spotting and realized she had missed her period entirely. A home pregnancy test and a visit to the doctor confirmed that her third child was on the way.
How many women have unplanned pregnancies?
Nearly half of pregnancies in the United States are unplanned.
A 2016 study published in the New England Journal of Medicine examined the rate of unintended pregnancy in the United States from 2008 to 2011 and found that 45 percent of pregnancies in 2011 were not planned. That’s 2.8 million unintended pregnancies, of which more than 40 percent would end in an abortion.
While the rate of unintended pregnancies declined from 2008 to 2011, the percentage of women who sought abortions for their unintended pregnancies changed very little. And in 2011, just like in 2008, unintended pregnancy remained most common among women and girls who were poor and those who were cohabiting.
“Lower-income women, rural women and women with limited access to health care will be disproportionately affected by these laws,” Dr. Horvath said. “Women of means will be able to travel to other states, or other countries, just as they did before Roe v. Wade.”
