Pregnancy Week 2 – Weekly Development

It’s week two but just like week one, you’re not technically pregnant just yet. It still counts as a part of your 40-week pregnancy journey anyway and you are definitely closer to that milestone than you were in week 1. The exciting thing about week 2 is that your body is gearing up to ovulate and this is a very big deal. 

Basically, getting pregnant involves a measure of calculations, it’s nothing special, so don’t be worried. Calculation in this sense refers to studying your cycle to identify the days that you are most fertile. 

This week, your baby is the size of a tiny fleck of pepper.

Typically, there are two days in which you are most fertile; two days before you ovulate and the day that your ovulation actually takes place. If your cycle is a regular 28-day one, then your ovulation should take place on day 15. But for most women, the 28-day cycle isn’t a regular every single month, it may vary from month to month. 

At week 2, you might not feel any different but you are definitely ovulating and is the best time to have sex in hopes of conception. If a sperm gets to your fallopian tube to meet a waiting egg during this time period, conception is bound to take place. 

After a few days, you might notice some very light spotting. You would probably assume that it is just your period, however, it is an indication that the egg that has already been fertilized has attached itself to your uterine wall. 

Your Baby’s Development

You already know that at this time, there is still no fetal development. However, the good news is that it is closer than you think and your body is getting ready. In your ovary, something monumental is happening, the egg is maturing and preparing to break free. 

In the meantime, your body already shed its old uterine lining and gotten rid of the unfertilized eggs from last month during your first week of pregnancy. Now, the lining of your uterus is beginning to experience new growth and it is getting thicker so that it can accommodate and support a new life. 

Right now, one egg has already become dominant. It is the estrogen that it releases that stimulates your uterine line to begin to thicken. 

When the estrogen levels are significantly high, this, in turn, triggers a rapid increase in the level of LH or luteinizing hormone which causes the already mature egg to break free from its follicle and find its way to the fallopian tubes. 

Follicle stimulating hormone or FSH also plays a major role and ensures that the egg or in certain cases, eggs mature and are released to bring about conception. This is of course known as the process of ovulation and the egg released then lives for 12-24 hours after ovulation. 

Its implication is that it isn’t super mandatory that you have sex on the exact day of your ovulation. Sperm can survive for up to five days in fertile cervical mucus. So, you can have coitus on any other day during the week you would be ovulating or even some days before you ovulate.

This way, the sperm is already in place and waiting for the egg to be released so that fertilization can take place. Millions of sperm typically begin the swim towards the egg, however, only the strongest and healthiest make it all the way to the fallopian tube. And only one makes the cut for fertilization. Once the sperm attaches to the egg, this is regarded as fertilization. 

Also, it doesn’t hurt to have sex on the day you’re ovulating and medically, it guarantees you a higher chance of conception. 

Your conception would typically occur at the end of pregnancy week 2 and the chromosomes in each cell would combine immediately after the egg has been fertilized by the sperm.

At this very moment, your baby’s genes would be determined. By the first few days of your pregnancy, the gender and genetic features of your baby would have already been determined. 

In the case of identical or monozygotic twins, a sperm fertilizes one egg which then divides into two equal halves and brings forth two living organisms. This would lead to children who are genetically identical and of the same sex too.  

The scenario of non-identical or dizygotic twins results when two sperm cells fertilize two different eggs. The babies that result from this biological process could either be of the same sex or of different sexes. And they would appear no different from siblings who were given birth to at different times. 

The fertilized egg otherwise known as zygote would start to divide into multiple cells and then travel all the way down to the fallopian tube within 24 hours of conception. 

Your Symptoms 

Week two is a part of the early days of pregnancy, so if there are going to be any changes, they would be very subtle. The main event during week two is ovulation, therefore, your symptoms for this week would be those that your body is showing to indicate that it is preparing to ovulate. 

Closely tracking these symptoms can help you to pinpoint your fertility period and significantly boost your chances of conception. Here are some of the most common symptoms of ovulation that you would notice: 

Basal Body Temperature Changes 

Keeping a close eye on your BBT is one of the ways to determine the precise moment when you would ovulate. Your BBT experiences a drop to its lowest point at the precise moment when you are ovulating and then rises by about half a degree. 

You would most likely get pregnant two or three days before the rise in temperature would occur. You would need a thermometer to measure basal body temperature. You should record your temperature every day and then wait for the pattern to become clear. 

Your temperature measurement should be at the same time every day; it is advisable to do it when you wake up. It usually takes a few months to clearly determine the pattern and you would need to time coitus such that it occurs before the rise in temperature. 

Change In Cervical Mucus 

Examination of cervical mucus is one of the ways women detect that ovulation is approaching. As ovulation approaches, your cervical mucus thins start to feel stretchy, become clear, and “egg white-lie”. These conditions aid sperm travel up the cervix. Also, vaginal discharge may appear different. Vaginal discharge during ovulation is clear and pretty slippery. The discharge becomes cloudier post evolution and it eventually disappears. 

Abdominal Pain

In certain cases, some women may experience a little twinge in their abdomen or slight discomfort when they release an egg. This symptom is otherwise known as Mittelschmerz. 

Mittelschmerz or middle pain refers to a dull and slightly throbbing or a sudden sharp pain that happens when the menstrual cycle halves and is usually felt on one side of the lower abdomen. 

It isn’t a persistent pain and is mainly linked to ovulation. However, it doesn’t occur in all women and for women who experience it, some claim that it doesn’t occur every month. Also, this pain can be caused by other reasons such as an upset stomach or gas. 

Therefore, although mittelschmerz could be indicative of an egg bursting out of the ovary, it isn’t a very reliable one. 

Increased Sex Drive

Around ovulation, the hormones involved in the entire process leading up to the release of the egg may increase sexual desire in women, especially around the time in her cycle when she is most fertile. This is nature’s way of nudging you to do what should be done. 

Other symptoms of ovulation include breast tenderness, a heightened sense of smell, feeling lightheaded or dizzy, cravings, or aversions to certain foods and light spots among others. 

Measures To Observe 

Typically, you should have begun to observe certain measures since the first week of your pregnancy. However, here are some measures that need to be emphasized for week 2:

Self Care 

Eating healthy and engaging in regular workouts as well as cultivating a good sleeping habit is necessary to keep you in prime health. Also, it helps you keep your weight in check and stay within the guidelines for weight gain during pregnancy. 

Stress Less 

Now is not a good time to stress extra. The basic everyday stress isn’t going to significantly affect you, but it is advisable to reduce it all the same. High

levels of stress borne of trying to conceive may have a negative effect on fertility.

Take Vitamins 

Continue taking the vitamins that you started in week one or if you haven’t started, week 2 is still a great time to start. Folic acid or some prenatal vitamin would supply you and your future baby with the necessary nutrients.

More Intimacy

When you’re trying to conceive, ensure that you don’t start to see sex as a chore. It is, in fact, a great time to build intimacy between you and your partner. 


Pregnancy week 2 isn’t any hassle at all. You’re basically experiencing the same things that you do every other month. However, you should keep in mind that the difference now is that you might be pregnant and therefore, act accordingly.
