10 Early Pregnancy Symptoms to Look Out For

Femometer Vinca can help you spot early pregnancy by keeping an eye on your BBT, but we know that many women like to look out for other symptoms too. Here are 10 early pregnancy symptoms you can look out for, but remember, many are similar to the signs your period is on its way. The best way to work out which is which? Keep a log in your Femometer app so you know your typical period symptoms.

Raised BBT

Time: 1 - 3 days past ovulation onwards

As many women on their TTC journey will know, continuous elevation of BBT after ovulation is a good sign. As progesterone increases, your body temperatures remain elevated. In the first trimester of pregnancy progesterone continues to rise, so it makes sense that your temperature should remain elevated. That said, not all women who get a positive pregnancy test will have had a continuously elevated BBT - so don’t lose hope if yours drops!

Mood swings

Time: 1 day past ovulation onwards

It’s really not surprising that mood swings are common in both ‘normal’ menstrual cycles and early pregnancy. For one, our ever fluctuating hormones affect our sleep, serotonin and melatonin, and each of these can affect our mood. Mood swings in early pregnancy are completely normal, excitement followed by anxiety followed by joy is expected! Once again hormones also play a part in this and our other symptoms, meaning that our mind and body are having to work doubly hard to keep things functioning as normal. Go easy on yourself and make sure you half down-time. 

Headaches and dizziness

Time: 6 - 14 days after ovulation

Cause / Interpretation: Headaches are a common early pregnancy symptom. They are usually harmless but can be uncomfortable. These headaches can be caused by an increase or change  in blood volume as well as fatigue (the body is working overtime to prepare itself for motherhood!), thirst, hunger and possibly even caffeine withdrawal. Ensure you’re drinking enough water and getting as much rest as possible. If your vision is blurred or you’re seeing flashes you should see a health care specialist as soon as possible.

Implantation bleeding

Time: 6 - 14 days after ovulation

Some women will notice light spotting around 7-10 days past ovulation. This light bleed can be caused by the embryo ‘burrowing’ it’s way into the lining of your womb and can sometimes be confused with the start of your period. Implantation bleeding can be pinkish-red or a darker brown discharge, both are normal. The bleeding itself won’t normally last longer than a day or two. If you’re concerned about bleeding and think you might be pregnant, it’s always best to visit your health specialist as soon as possible.

Implantation pain and mild cramping

Time: 6 - 14 days after ovulation

Just like many women many feel a small twinge of pain when they ovulate, some women also find they are able to pinpoint the implantation of the embryo into the uterus lining. Mild cramping is a common early pregnancy symptom that is often confused with period pains. The cramping is caused by the changes in the womb as the body prepares for pregnancy. 

Sore breasts

Time: 6 - 14 days after ovulation

Many women already recognize the changes in their breasts through their typical cycle, but sore breasts in pregnancy can feel even fuller and heavier than usual. Breast soreness as an early pregnancy symptom may mean that your breasts feel painful to touch and that some of your ‘usually comfortable’ underwear feels impossible to wear! Breast changes and sensitivity are caused by the increase in progesterone levels that occurs in early pregnancy and will usually start 1-2 weeks after ovulation. Essentially, these symptoms can be blamed on the body preparing to be a feeding machine for a hungry baby!

Sensitive nipples

Time: 6 - 14 days after ovulation

Sensitive nipples are a common early pregnancy symptom. You may feel tingling or slight pain. You may find that your nipples are much more likely to be erect than usual and feel uncomfortable against clothing. You nipples may become darker and you might see more little bumps that look like goose-bumps which are actually lubricant supplying glands.

Nausea and sickness

Time: 6 - 14 days after ovulation

Nausea in early pregnancy, often referred to as morning sickness, usually starts around 6 weeks into pregnancy, around 2 weeks after your missed period. Despite its name it can happen day or night, and for some poor women, it can be present constantly in the first trimester. Doctors aren’t 100% certain of the cause of morning sickness, but the most popular theory is that it’s caused by the body’s reaction to the pregnancy hormone human chorionic gonadotropin, HCG for short.


Time: 6 days past ovulation onwards

Feeling more sleepy than usual? This is a very common early pregnancy sign. An increase in progesterone after ovulation can be blamed for some of this sleepiness. The second reason for feeling fatigued is the increase in blood volume in your body, this means the heart has to work harder. Finally, it’s also thought that lower blood sugar can add to a feeling of general tiredness.

Hunger/Food cravings

Time: 6 days past ovulation onwards

Although food cravings are usually associated with later pregnancy, both cravings and aversions can be seen in very early pregnancy. It’s thought that this is closely linked to changes in taste and an increased sense of taste and smell. This could be explained by the fact that taste and smell are partially controlled by estrogen which increases rapidly in the first trimester. Cravings are also sometimes thought to be caused by the body attempting to increase levels of certain nutrients that it requires.
