While abortion pills are safe and effective, not many are sure how early or further in pregnancy they can use the medication. Or, they may not have a complete awareness about the timeline for medical pregnancy termination, the break time between administration of Mifepristone and Misoprostol, and what to expect thereafter.
So, in this blog, we will discuss use of pills to end an early pregnancy and related duration, with additional information.
What is a Medical Abortion – The Pills to Use
Before understanding the timing of the pill use, let us study the instructions for their administration and action mechanism:
·
The first pill, Mifepristone 200mg is swallowed orally with water. Take the medicine to start the abortion, irrespective of food.
·
After 24 to 48 hours, use Misoprostol 200mcg x 4 pills vaginally / buccally / sublingually. This prostaglandin medicine results in pregnancy expulsion by causing uterine contractions. It may lead to heavy vaginal bleeding, nausea, abdominal cramping and pain.
·
The preferable method is using both the abortion pills. However, Misoprostol is often used alone if Mifepristone is not available. The pills are used 4 at once at a gap of 3-4 hours each, a maximum of up to 5 times as per decision of a healthcare professional.
Gestational Age vs. Date of Conception – Detecting Pregnancy
The medicine-assisted pregnancy termination can be followed if:
·
The pregnancy is less than 10-12 weeks. The conception is within the uterus and not located outside it. You can count the gestational age from the first day of your last menstrual period (LMP).
·
You may use a home pregnancy test to check for human chorionic gonadotropin (hCG) levels that indicate a pregnancy, or undergo an ultrasound scan for better accuracy regarding pregnancy weeks and location.
·
Remember that the date of conception is not the date from when the gestational age is calculated. As ovulation and pregnancy are apart by two weeks from the beginning of a period, it is estimated to be 2 weeks since conception but at 4 weeks of gestation.
Importance of Ultrasound Pregnancy Test Before Abortion
Apart from the home pregnancy test, this is why doctors prefer ultrasound scan to determine pregnancy details and medical eligibility for the abortion pill process:
·
Since a medical abortion is unsuitable for ectopic pregnancies, healthcare providers await an ultrasound to confirm if the conception is within the uterus or outside.
·
The test in question provides a clearer view on pregnancy at 5 to 6 weeks LMP to understand if the fertilized egg is implanted in the uterus or not.
·
However, certain medical organizations recommend taking the pills before ultrasound visibility of the gestational sac, provided a suspected ectopic pregnancy and signs of it such as one-sided but severe pain in the pelvis or unexpected spotting.
·
The doctor may ask for hCG levels to check if the ultrasound was not sufficient to detect the pregnancy, if it is too early. If using a high-sensitivity pregnancy test at home, the hCG levels are easily detected.
·
If the abortion is initiated earlier than 5 weeks, repeat the blood or urine test weeks later to check for abortion outcome.
Why Terminating Pregnancy Early is Better?
Ending pregnancy early allows you the option for medical abortion, and many other benefits:
·
Medication abortion is a higher success rate of over 98% when done early in the initial 8 to 9 weeks.
·
The symptoms of abortion pill process are milder at 4 to 6 weeks pregnancy as the embryo is quite less developed.
·
Since ending an early pregnancy has fewer physical and emotional impact, the overall stress and anxiety or risk of complication, is also less.
·
If a pregnancy is beyond 10 to 12 gestational weeks, in-clinic invasive procedures like duction or dilation and evacuation are the options, but not abortion pills. So, making a decision early to end a pregnancy is helpful in many ways.
What to Expect During an Early Medication Abortion?
If you choose abortion pills for early pregnancy, here is a brief about the overall process:
·
Firstly, you must undergo a medical assessment to understand the gestational age, pregnancy location, and discussion about precautions, contraindications, interactions, along with understanding the medical abortion procedure in detail.
·
Once you receive the pills, use Mifepristone on day 1 and after 24 to 48 hours, take Misoprostol pills. After the last medicine dose, expecting cramping and bleeding to start in 1 to 4 hours.
·
After the pregnancy is expelled, the side effects will begin to reduce, with light bleeding or spotting continuing for a few weeks. Follow-up to check abortion result after 14 days of the procedure via an ultrasound pregnancy scan.
