It is normal to worry if you’re pregnant or your menstrual cycle is late at 16 DPO. After conception, it may take some time before you start experiencing pregnancy signs and symptoms.

Let’s discuss the most common pregnancy symptoms experienced by most women at 16 DPO and the meaning of a negative result after taking a pregnancy test.

16 DPO Pregnancy Symptoms and Signs: How to Know If You’re Pregnant

16 Days Past Ovulation Symptoms

At 16 days past ovulation, it is possible to know if you’re pregnant because the human chorionic gonadotropin (hCG) levels are usually high enough to be detected by a pregnancy test. You may also start experiencing early symptoms of pregnancy during this time. However, many women also experience symptoms of premenstrual syndrome (PMS) at 16 DPO. Women who are aware of the regular changes in their bodies every month may be able to tell if they’re experiencing PMS or if they are pregnant at 16 DPO.

Early pregnancy symptoms at 16 DPO

The most commonly experienced symptoms at 16 DPO are:

  • A missed period – Missed or late period is one of the most known signs of early pregnancy. However, women with an irregular cycle should not consider this symptom to indicate that they are pregnant. If you miss your period, you need to wait for a few days and take another pregnancy test. It gives you enough time to ensure that you did not miscalculate your dates or to know if your period is just late. If the test turns out positive after waiting for a few days, it means that you’re pregnant. If it turns out negative, it might mean you’re not pregnant. Other common causes that may result in a missed period are hormonal imbalances or medical conditions. 
  • Tender and swollen breasts – During pregnancy, your body undergoes hormonal changes that cause your breasts to become heavy, sore, swollen, and tender. You may also start noticing that your nipples have become darker. Within a couple of weeks, your body will adjust to the hormonal changes, and the symptoms will get better. Breast pain is a common early pregnancy symptom. But if the pain becomes unbearable, you should see a doctor. Your breasts will become heavier and larger than before, and your nipples will also begin to produce some discharge as your pregnancy progresses.
  • An elevated/raised basal body temperature (BBT) is normal for your body temperature to increase after ovulation and go back to normal after receiving your periods. But, if you’re pregnant, your BBT will stay elevated throughout your pregnancy. After your ovaries release an egg, there is an increase in the production of progesterone hormone, which in turn increases your basal body temperature. However, if implantation of a fertilized egg fails to occur, the basal body temperature and progesterone levels get back to normal before your period.
  • Vomiting or nausea – Although many know it as morning sickness, nausea can occur day or night if you’re pregnant. Morning sickness usually begins one month after conception. However, it may start sooner for some women, and it may never show up for others. The leading cause of nausea during pregnancy is unknown, but it is believed that pregnancy hormones play a significant role. If you experience severe vomiting and nausea such that you cannot keep food down, you need to visit your doctor as soon as possible.
  • Fatigue – Fatigue is a common pregnancy symptom 16 days past ovulation. It is caused by high progesterone levels during the early weeks of pregnancy, making you feel sleepy, exhausted, and tired. Your body also experiences increased exhaustion because it produces more blood for the growth and development of the fetus. If you’re experiencing fatigue, you need to get plenty of sleep and rest. It would also be nice to accept help from family and colleagues. Look after your physical health and ensure you take a healthy and balanced diet. Fatigue cannot harm your baby, but it can make your life difficult, especially during the early days of pregnancy.
  • Moodiness – During early pregnancy, the surge of hormones may make you feel weepy or emotional. However, it is also normal to have mood swings during this time. Like women who experience irritability before getting their period every month, it’s the same way some struggle with anger and frustration during pregnancy. Physical discomfort and fatigue also contribute to pregnancy anger. While it is normal to experience frustration, you need to ignore your anger if it interferes with your day-to-day life. To cope with pregnancy mood swings, you need to be patient with yourself and prioritize sleep and rest.

16 DPO BFN: can you still be pregnant?

At 16 DPO, there are minimal chances of a false-negative pregnancy test result. However, many reasons can contribute to getting a false negative result at 16 days past ovulation. Some of the most common reasons are taking the test too early or miscalculating when you’re supposed to get your next period. Taking a test too early may provide a false-negative because the hCG levels in your urine are too low to be detected by a home test.

A false-negative hCG result may also be caused by diluted urine. For example, taking a urine test after consuming plenty of fluids can dilute the collection resulting in a false negative.

HCG levels at 16 days past ovulation

During pregnancy, the placenta forms leading to the production of hCG. Pregnancy can detect hCG in urine 12 to 15 days after conception. After every 48 to 72 hours, hCG can double. hCG levels are highest at week ten and afterwards decline and remain steady throughout your pregnancy.

HCG levels are recorded as a milli-international unit of hCG hormone per millilitre of blood (mIU/ml). Home pregnancy tests can either show a positive or negative result which means that they are qualitative. Such tests are designed to detect levels of hCG from 10 to 50 mIU/ml. However, blood tests can measure low levels of hCG from 1 to 2 mIU/ml.

Blood hCG pregnancy test results

For a positive result, blood hCG pregnancy test results the hCG level needs to be greater than 25 mIU/ml. This means that an hCG of 5 mIU/ml will produce a negative result on a home pregnancy test but be detectable when you take a blood test. Anywhere between 6 and 24, mIU/ml will only produce an equivocal result, and you will have to take another test later.

hCG tests are of two kinds. First, there is a quantitative test that measures the amount of hCG found in your blood. The second kind is there qualitative test used to detect hCG presence in your urine. Unfortunately, different laboratories have different hCG normal ranges. It means that the test results may vary slightly. Therefore, it is essential to consult with your health care provider to get an accurate interpretation of your test result.

16 DPO and no period: what could it mean?

If you fail to get your period at 16 DPO, there are high chances that you’re pregnant. This is because ovulation happens between the 13th and 20th day of your menstrual cycle (from the first day of your period). The exact day you ovulate is determined by the length of your cycle. However, most women receive their period around 16 DPO. Therefore, if you don’t start your period by 16 DPO, you are probably pregnant. If you have conceived, you may begin to experience symptoms such as elevated BBT, breast tenderness, moodiness, and fatigue.

16 DPO negative pregnancy test

If you experience early pregnancy symptoms and get a negative test result at 16 DPO, you should do another test after several days. Alternatively, you can visit your health care provider and have them take a blood test for more accurate results than urine pregnancy tests.

At 16 DPO, it can be confusing to know if your period is late or if you’re pregnant. If you’re expectant, you may start noticing some symptoms. Some of the most common symptoms and signs of pregnancy at 16 days past ovulation are frequent urination, moodiness, fatigue, nausea, tender and swollen breasts, and an elevated BBT. In most cases, if you get a negative test result at 16 DPO, it is usually a sign that you are not pregnant. However, to be sure, you need to do a repeat test after a few days, especially if you have early pregnancy symptoms.
