Even though the pregnancy symptoms of the first trimester have settled completely, your body starts behaving in strange ways. The physical changes happening to you during week 21 are as follows:

Another form of birth control would be the birth control pill. The pill is made of hormones, estrogen and progesterone which keep the eggs from leaving the ovaries. There is also another form of birth control called the birth control implant which is a thin, flexible plastic implant that is inserted in the upper arm. The implant will last up to three years and releases progesterone which prevents the eggs from leaving the ovaries. Pregnancy cannot happen if there is no egg for the sperm to join to (Planned Parenthood). The normal stages of development in the fetus during the first weeks after conception is the when the second degree oocyte and the sperm undergo capacitation, when the secretions from the female, the hard membrane of the sperm breaks down and becomes fragile which allows hydrolytic enzymes to be released when it comes in contact with the oocyte. After sperm enters into the egg, it then completes meiosis II, the ovum and sperm swell causing female and male pronuclei. The pronuclei then finish fertilization and become a zygote. The zygote then undergoes many stages of division and becomes a blastocyst and implants in the endometrium of the uterus. This all happens within six to eight days. Some of the hormonal changes that might occur after becoming pregnant are large amounts of oxytocin being produced, which is inhibited until labor. Oxytocin stimulates the uterus to contract (Hendry, C). Prolactin, progesterone, and estrogen levels also rise

At week number thirty five, you should be delighted to know that your little one playing inside looks just like a little new born should and yes, it is just a matter of a few days till you can see and feel him or her in person! However as the day of labor comes closer, most of the pregnant women tend to panic and feel anxious as to how their pregnancy would go. While this is nothing but extremely normal and usual a happening, it is important to share the worries with your medical practitioner so that she can closely monitor your and your babies health in the due course of time.

Each month inside your ovaries, a group of eggs starts to grow. Eventually one of the eggs erupts from the follicle and this is known as ovulation. It usually happens about two weeks before your next period. A hormone is released that helps thicken the lining of your uterus, getting it ready for the egg. After the egg is released, it

Conception also known as fertilisation is the fusing of two gametes. This creates an embryo which will eventually develop into a baby. All human life begins with conception. A fertile woman will usually produce one egg a month around 2 weeks after the last menstrual period.

There are some obvious changes during the first trimester like your periods stop that let you know whether you are pregnant. You will notice the changes in your breast like darken area around your nipples. You will experience the unexpected mood swings which are quite normal.

They extend about 4 inches laterally from either sides of the uterus to the ovaries. It is in the fallopian tubes that fertilization normally occurs. The tube transports the ovum, or egg, from an ovary to the uterus, but the tubes do make direct contact with the ovaries.

eggs will essentially mature. Contrary to women, a man begins producing sperm at puberty, which gradually decreases along with age. During the actual conception, over 200 million sperms head towards the egg and try to break through. One is successful, the rest aren’t.

Also the release of FSH and LH and will stop the body to release the egg to get fertilize. Because estrogen and progesterone controls the hormone levels in a female in return will stop estrogen from increasing during the cycle. If progesterone remains high this will stop FSH and LH from releasing this will cause the egg from maturing and will stop the ovulation process.

A woman only makes on egg and it doesn’t fully separate after fertilization, the growing baby starts to separate but stops before the process is complete.

Conception: Out of hundreds of eggs and millions of sperm, only one egg and sperm join together at conception. This process takes place in women fallopian tube. The fertilised egg moves to towards uterus to implant in it for next nine months. During this journey, the zygote divides into 12 to 16 cells before reaching the uterus.

During the first half of your cycle, the cervix will feel relatively firm and dry. The cervix will be positioned low and easy to reach. The entrance of the cervix will feel closed. Before ovulation, the cervix will become soft and moist. The entrance of the cervix will feel open. During peak ovulation, the entrance of the cervix will increase to it's maximum and it may be difficult to reach with your fingers. Ovulation Sign: Mittelschmerz

The menstrual cycle is something that a lot of girls and even guys have questions about. The menstrual cycle is something that only girls go through once they experience puberty. It is nothing more then the route of an egg through the female’s reproductive system. The menstrual cycle starts as the egg matures in the ovary. The egg is then released from the ovary during the process called ovulation. The egg then travels in the fallopian tube until it reaches the uterus. If it is not fertilized by a sperm, through fertilization, then it out of the body in a process known as menstruation, or a period.

For many women, the typical signs of pregnancy are when their period doesn't arrive on time, providing they've been active sexually. But can you be pregnant and not know it? There are some factors that might conceal the pregnancy, even more than six weeks. Taking into consideration all the mental and physical changes that usually happen to expecting moms, it’s hard to believe how a woman couldn’t possibly know. Truth be told, the experience called a cryptic pregnancy, isn’t so uncommon.

The reproductive role of the female is far more complex than that of a male. Not only must she produce gametes, but her body must prepare to nurture a developing embryo for a period of approximately nine months. Ovaries, the female gonads, are the primary reproductive organs of a female, and like the male testes, ovaries serve a dual purpose: They produce the female gametes (ova) and sex hormones, the estrogens * and progesterone (pro-ges′tĕ-rōn). The accessory ducts (uterine tubes, uterus, and vagina) transport or otherwise serve the needs of the reproductive cells and a developing fetus.
