Conception Pregnancy Ovulation, Fertilization, and More. Most of the time, you wont know the exact day you got pregnant. Your doctor will count the start of your pregnancy from the first day of your last menstrual period. Thats about 2 weeks ahead of when conception happens. Heres a primer on conception Ovulation. Each month inside your ovaries, a group of eggs starts to grow in small, fluid filled sacs called follicles. Eventually, one of the eggs erupts from the follicle ovulation. It usually happens about 2 weeks before your next period. Hormones Rise. After the egg leaves the follicle, the follicle develops into something called the corpus luteum. The corpus luteum releases a hormone that helps thicken the lining of your uterus, getting it ready for the egg. The Egg Travels to the Fallopian Tube. After the egg is released, it moves into the fallopian tube. It stays there for about 2. All this happens, on average, about 2 weeks after your last period. If the Egg Isnt Fertilized. If no sperm is around to fertilize the egg, it moves through the uterus and disintegrates. Conception, the beginning of life. Explore the amazing journey from egg to embryo. A zygote from Greek zygtos joined or yoked, from zygoun to join or to yoke, is a eukaryotic cell formed by a fertilization. Your hormone levels go back to normal. Your body sheds the thick lining of the uterus, and your period starts. Fertilization. If one sperm does make its way into the fallopian tube and burrows into the egg, it fertilizes the egg. The egg changes so that no other sperm can get in. At the instant of fertilization, your babys genes and sex are set. If the sperm has a Y chromosome, your baby will be a boy. If it has an X chromosome, the baby will be a girl. Implantation Moving to the Uterus. The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 2. 4 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus. This is called implantation. Some women notice spotting or slight bleeding for 1 or 2 days around the time of implantation. The lining of the uterus gets thicker and the cervix is sealed by a plug of mucus. It will stay in place until the baby is ready to be born. Continued. Within 3 weeks, the cells begin to grow as clumps, and the babys first nerve cells have already formed. Pregnancy Hormones. A pregnancy hormone known as h. CG is in your blood from the time of implantation. This is the hormone detected in a pregnancy test. Usually it takes 3 to 4 weeks from the first day of your last period for the levels of h. CG to be high enough to be found by the tests. Sources. SOURCES Springfield Technical Learning College. The Merck Manual. 2. Web. MD, LLC. All rights reserved.

Everything You Need to Know to Get Pregnant. What does ovulation mean When will you be ovulating And what does it have to do with getting pregnant If youre new to trying to get pregnant, or youre just trying to understand the female reproductive system a little better, you may have basic questions like these. Maybe you feel embarrassed to ask your doctor because you feel like everyone knows the details already. But the more information you have about ovulation, the better prepared youll be for the whole pregnancy process. What Exactly Is Ovulation Ovulating is what happens when an egg, or ovum, is released from the ovaries. During each menstrual cycle, reproductive hormones work together to stimulate the ovaries. A few immature eggs, also known as oocytes, begin to grow and respond to those hormones. Even though several oocytes will start developing at the beginning of the cycle, usually only one egg will be released. If two eggs are released, you may conceive non identical twins While the ovaries are preparing to release an egg, the uterine lining endometrium is getting ready to receive a fertilized egg, or embryo. Hormones lead to the thickening and changing of the endometrium. You might assume that the eggs in the ovary develop from the first stage to ovulation in a months time, but thats untrue. Oocytes develop over several months. They go through various stages until they are either ready to ovulate or stop growing and remain dormant. Most of the eggs in a womans ovaries never mature to ovulation. When a woman begins puberty, the ovaries house approximately 3. Despite this apparent storehouse of eggs, a woman only ovulates around 3. There is also a misconception that each ovary takes a turn ovulating every other month. For example, one month the right ovary ovulates. Then the next month, the left ovary ovulates. In fact, ovulating occurs on whichever side has the most mature ova or ovum of the month. In some women, one ovary may ovulate significantly more often than the other. When Will I Ovulate Ovulation usually occurs between day 1. Each woman ovulates on her own schedule. Youve probably heard that ovulation occurs on Day 1. In fact, even women with 2. Day 1. 4. One study found that fewer than 1. Day 1. 4. Usually, when a woman says she is ovulating, shes referring to the especially fertile period of two to three days that precede ovulation. If we assume ovulation occurs somewhere between day 1. Day 2. 2. Thats a wide range This is why most women who want to conceive will track ovulation and fertile signs. How Will I Know Most women experience signs and symptoms before ovulating. Some symptoms may appear several days before ovulation, while others wont happen until the day before or day of ovulation. Signs and symptoms that occur before ovulating include an increase in sexual desire, an increase in cervical mucus, softening and opening of the cervix, and ovulation pain ovulating is not usually painful, but some women report feeling a cramp or sharp pain on their side. Signs and symptoms of ovulating that occur on the day or days after include the reverse symptoms a decrease in sexual desire, a decrease in cervical mucus, a rise in body basal temperature, and breast tenderness usually several days after ovulation, sometimes mistaken as an early pregnancy sign. Another option is to use ovulation test kits. These tests work a lot like pregnancy tests, in that you use your urine to determine whether a particular hormone is present. When you get a positive result on an ovulation test, youre approaching ovulation, and you should have sex. Ovulating and Pregnancy. Conception requires at least one ovum and one sperm. Semen can live three to five days in the female reproductive tract. So if a couple has sex on Monday, there will still be live, viable sperm hanging out in the womans fallopian tubes on Thursday. The human ovum, however, lives just 2. It must be fertilized within the first 1. This is why you need to have sex before you ovulate. If you want to get pregnant, sex before ovulation will ensure there are sperm cells waiting to greet the ovulated egg. Theres no need to have sex at the very moment of ovulation. When Are You Considered PregnantWhen a sperm cell fertilizes the egg, conception takes place. But you are not technically pregnant in this moment. To be considered pregnant, the fertilized egg must implant itself into the endometrium. This happens 7 to 1. This is why a woman who is going through IVF isnt considered to be pregnant after embryo transfer. Even though the embryo has been transferred to the uterus, shes not pregnant unless the embryo implants itself into the endometrium. How Often Should You Have Sex While knowing when you are ovulating can help you time sex for your most fertile days, its not required. If you have sex three to four times a week, youre bound to have sex around your ovulation period. What If Im Not OvulatingIf you dont experience any ovulation symptoms at any time during your cycle, or if you have irregular periods, you may not be ovulating every month. Anovulation is when a woman does not ovulate. It is a common cause of infertility. Other possible symptoms of anovulation are extremely short or long periods or a complete absence of menstruation. A Word From Verywell. If you want to get pregnant, you need to have sex on the days leading up to ovulation. There are a variety of ways to detect and track ovulation, but you dont need to stress over it. If you have sex three to four times a week, youre bound to have intercourse on one of your fertile days. If youre not having regular periods, you may not be ovulating. This can be a possible sign of infertility. While usually couples are told to try on their own to conceive for at least six months to a year, if you have symptoms of a problem, that timeline doesnt apply. Talk to your doctor sooner than later. Earlier diagnosis can improve your odds of successful treatment. Source European Society of Human Reproduction and Embryology. Accurate prediction of ovulation to help women become pregnant.
