Egg Fertilization Symptoms

Egg Fertilization Symptoms

If you are pregnant, the egg fertilisation happens in the 2nd week. However, you might have doubts about your conception until you do a home pregnancy test. Healthcare providers count your due date from your last menstrual period. And technically, it is your first day of your pregnancy. As you have ovulation around two weeks in your menstrual cycle, conception takes place around the time you are 2 weeks pregnant. It means your pregnancy begins before you conceive. 

Ovulation period - the best time to conceive 

Usually, you ovulate in the middle of your menstrual cycle. At this time, you are highly fertile. Changes in basal body temperatures, mild cramps, breast tenderness, and enhanced vaginal discharge are the signs of your ovulation period. You can detect your ovulation with the use of ovulation test strips. And this detection can help you know the best time to have unprotected vaginal sex to get pregnant.   

The development of baby at 2 weeks pregnancy

In the 2nd week, you are getting ready to raise a baby in your womb. The increase of progesterone and oestrogen hormones prompt the uterus lining to thicken. This thickness facilitates egg fertilisation. In the meantime, your eggs get matured and turn into fluid-filled sacs, follicles, in your ovaries.   

At the time of ovulation, there is extraction of an egg from its follicle and transportation of the egg into one of the fallopian tubes. Ovulation can take place at any day between days 9 and 21 of your menstrual cycle, which is normally 28 days.    

Egg fertilisation 

During the next day, the egg will have fertilisation with one of 250 million sperm from the ejaculated semen into your vagina. The ejaculated sperm swims from your vagina to cervix, uterus, and the fallopian tube to get into the egg. Approximately 400 sperm survive after 10 hours of journey from the vagina to the uterus and the fallopian tube. However, only one sperm succeeds in egg penetration.  

There is a merger of sperm’s nucleus with the egg’s during the next 10-30 hours. The combination of their genetic materials takes place. You will give birth to a baby boy if your male partner’s sperm carries a Y chromosome. Otherwise, you will have a baby girl. After fertilisation, the egg is a zygote.  

In the next 3-4 days, the egg travels to your uterus from the fallopian tube. It has a separation into more than 100 identical cells in the journey from the fallopian tube to the uterus. After getting into your uterus, it is blastocyst. Later on the day 1 or 2, it will start burrowing into your uterus' lush lining where it continues to divide and grow.     

Pregnancy symptoms or egg fertilisation symptoms during the 2nd week 

As your egg starts fertilisation with your male’s sperm, you can notice a few signs. Here are some significant egg fertilisation symptoms:

  • Mild cramping 
  • Slippery cervical mucus 
  • Increased sex drive 
  • Cervical changes 
  • Breast tenderness 
  • Increase in your basal body temperatures  

How to manage the symptoms of 2 week pregnancy 

Except for a few cases, you can easily handle your pregnancy of 2 weeks. Here are some steps you should follow:

  • Consult your doctor - As you plan your pregnancy or conceive, you should consult a gynaecologist/obstetrician. The doctor will help you get ready for pregnancy, how to carry it successfully, and more allied things.   
  • Take this blood test - Before you start working on your pregnancy plan, both of you should have genetic carrier screening. It will help you be sure about having a healthy and cute baby.  
  • Take your vitamins - Whether you are on your pregnancy journey or have just conceived, you should take vitamins and minerals. Include iron, folic acid, vitamin D, and calcium in your diet for the better health of your child and yours.  
  • Sex frequently - You should have unproted physical intimacy daily to increase your chance of having a conception. Before making any announcement, you should try more and get it confirmed through tests. 
  • Have time for self care - You should have time for yourself, especially when you are trying to conceive or newly pregnant. Sleeping soundly, exercising regularly, having a balanced & healthy diet, lowering your stress levels, etc. are the things you need to do for your selfcare.   
  • Prepare your body and mind for pregnancy - You need to prepare your mind and body for pregnancy. In this, you should learn about the changes that happen to your body and in your mind. Through light to moderate exercises, you should strengthen your body parts to be ready for carrying extra weight. To train your mind, you should work on mind-body techniques. You can meditate and use affirmation tricks to stay positive.  
  • Educate yourself on what to do and what not to do during pregnancy - You should educate yourself whether you are on your pregnancy plan or newly pregnant. Have a safe distance from drinking alcoholic beverages, smoking, caffeinated drinks, and tobacco products. Your doctor will explain or you should discuss this with him/her.   


Egg fertilisation starts on the next day of your unprotected physical intimacy after the ovulation period. It brings some changes in your body that you can easily manage yourself. After noticing pregnancy symptoms, you should consult a doctor.
