Your body begins to prepare for the changes soon after conception. The hormones work in sync to support a new life. Oestrogen is one of the hormones that rises at the earliest. It is often referred to as the female hormone, but it triggers many subtle changes in your body during early pregnancy.
In this article:
What Exactly Is Oestrogen and What Does It Do?
Oestrogen is a hormone responsible for maintaining the function of your reproductive system. It regulates your menstrual cycle and supports the development of eggs. Other roles include maintaining the health of your bones, skin and heart. However, its role during pregnancy changes completely.- It thickens the uterine lining, making it easier for the embryo to implant
- It increases blood flow to the uterus and placenta
- It helps your body adapt to carrying a baby by relaxing joints and preparing your body for breastfeeding
When Does Oestrogen Start Rising After Conception?
A blastocyst forms right after fertilisation, which is a small ball of cells, and travels to the uterus so that it can implant itself in the lining. This process happens around 6 to 10 days after ovulation. Your body gets the cue to produce human chorionic gonadotropin (hCG) after implantation.The hCG hormone signals your ovaries to continue producing oestrogen and progesterone. Normally, they would drop during your period. Therefore, oestrogen levels rise quickly and also double every few days during the early pregnancy stages. They may rise to three to five times higher than they were before conception.
Why Does Your Body Need So Much Oestrogen So Fast?
Oestrogen levels increase for various reasons.- Oestrogen keeps the uterine lining thick and rich in nutrients, allowing the embryo to continue growing
- In early pregnancy, oestrogen helps form the placenta, which is the organ that supplies oxygen and nutrients to your baby
- It balances progesterone and hCG levels, maintaining a stable hormone environment for your pregnancy
- Oestrogen contributes to the formation of vital organs in your baby, such as the heart and brain
What Physical and Emotional Changes Might You Notice?
Oestrogen is responsible for the early pregnancy symptoms, as it is the first one to rise rapidly.- Tender or swollen breasts due to tissue growth
- Nausea and morning sickness are influenced by estrogen, which affects digestion and the feeling of nausea
- Fatigue and mood changes because oestrogen impacts your serotonin levels
- Increased vaginal discharge to protect against infections
- Heightened sense of smell or taste
What Happens to Oestrogen Later in Pregnancy?
The placenta produces oestrogen from around the 10th to 12th week of pregnancy. The levels continue to rise steadily after this stage until the delivery of the baby. Your oestrogen levels become 30 times higher than they were before conception. It is necessary for the following functions:- Keeps the uterus flexible for the growth of your baby
- Prepares your body for labour
- Encourages milk duct development for breastfeeding
What Can You Do to Support Healthy Hormone Balance?
You can support hormonal health during pregnancy through various simple steps.- Eat healthy meals that include fresh fruits, vegetables, whole grains, and protein to maintain stable energy levels.
- Water helps your body flush out waste and manage hormone activity, so increase your fluid intake.
- Activities like walking or prenatal yoga are beneficial for improving circulation, which helps reduce swelling.
- Your body uses a significant amount of energy adjusting to hormonal changes, so consider taking a rest during the day and getting a good night's sleep.
- Avoid unnecessary supplements or herbal products without informing your doctor.
When Should You Talk to Your Doctor About Hormone Levels?
- Intense feeling of nausea that prevents you from eating (possible hyperemesis gravidarum)
- Persistent headaches or vision changes
- Rapid weight gain or extreme swelling
- Feeling anxious, sad, or irritable easily
The Emotional Side of Hormonal Changes
The emotional effects of oestrogen are equally intense as the physical ones. You may feel overly sensitive or emotional without any clear reason. They are the result of the hormonal changes happening in your body.Talk about your feelings with your family or partner so that you feel cared for. The emotional support from your loved ones in such times can give you the strength to deal with your mood. Take small breaks from daily chores, or practise breathing exercises to gain a sense of balance.
Oestrogen levels rise quickly after conception because your body is preparing for a new life. The rise is essential for your uterus, placenta, and hormones to all work together seamlessly.
Going through these changes can be physically and emotionally draining, but understanding the reasons can help you stay calm. Do not hesitate to reach out to your doctor if any of the symptoms feel unusual to receive instant medical support.

FAQs on Why Oestrogen Levels Rise So Quickly After Conception?
- How soon after conception do oestrogen levels start to rise?
Oestrogen may start rising within a few days after the implantation occurs. It is usually around one week after ovulation. It continues to rise slowly throughout the pregnancy. - Can low oestrogen affect early pregnancy?
The uterine lining may not be able to support an embryo without sufficient oestrogen levels, leading to complications in early pregnancy. Your doctor may closely monitor your case and suggest treatment if necessary. - Are mood swings normal when oestrogen rises after conception?
Oestrogen affects the hormone called serotonin, which influences your mood. Feeling more emotional or sensitive over minor things is normal during early pregnancy.
