13 DPO: Milestone In Your Early Pregnancy Journey

Content

13 DPO (days past ovulation) is a milestone in your early pregnancy journey.

It’s tempting to take a pregnancy test at 13 DPO – but can you?

Read on for more information about what happens at 13 DPO and if it’s too early to test pregnancy.

What Happens at 13 DPO?

Conception happens when a sperm enters an egg. This occurs in the fallopian tube after ovulation, generally between day 10 and day 21 of a woman’s cycle. 

A fertilized egg then travels down toward the uterus, and after it reaches the uterus, implantation takes place around 6 days after ovulation or on day six of a woman’s cycle.

So by day 13 DPO, you will notice some early pregnancy symptoms.

Is 13 DPO Too Early to Test Pregnancy?

13 DPO is not too early to test pregnancy. Most home pregnancy tests have high accuracy at 13 or 14 DPO.

However, it might be too soon to test for pregnancy if you are trying to avoid becoming pregnant.

So if the condom breaks, make sure you use emergency contraception within 24 hours.

Pregnancy Symptoms at 13 DPO

Some women might experience some pregnancy symptoms at 13 DPO. These include:

13 DPO Cramps

Some women might experience cramps in their lower abdomen. They are mild in intensity, but they might be frequent. You might encounter them mainly in the lower abdomen, or they might be felt throughout the abdomen. Cramps are one of the earliest pregnancy symptoms, but they are not very common.

Fatigue

If you are pregnant, you will be highly fatigued in the early stages of pregnancy. If it is your first pregnancy, you might even miss a day’s work or school.

Once the egg implants into the uterus, the woman’s hormones enter a new stage and mimic that of a pregnant woman. Some women experience fatigue early on in their cycle during ovulation itself.

On the other hand, the common reason for this is increased pregnancy hormones in the body.

Progesterone levels are higher now. Some alterations to the circulatory system occur at this time. Blood vessels expand to provide a sufficient quantity of blood to the uterus, which may cause blood pressure levels to drop and contribute to tiredness.

Breast Changes (Breast Tenderness)

At 13 DPO, nipples and areolas may grow larger, engorged, and darker in hue during pregnancy. This may be accompanied by aching breasts or nipple tingling, or discomfort.

High progesterone levels are caused by these changes, which are produced first by the corpus luteum (a temporary endocrine gland in female ovaries) and then by the placenta.

Morning Sickness

The official name for nausea and vomiting in pregnancy is morning sickness. However, it is not always experienced in the morning. Morning sickness can happen any time of day or night. It might ease off for a few hours before starting again, especially during the second trimester when the growing uterus presses on your stomach.

The human chorionic gonadotropin (hCG) levels in the body begin to rise after fertilization once the egg has implanted. Every 48 hours, this hormone’s levels nearly double, reaching their peak around 8–10 weeks. It has been linked to morning sickness, and studies have shown that women with higher hCG levels reported more nausea throughout their pregnancy.

13 DPO Implantation Bleeding

Implantation bleeding is a common experience among women who experience early pregnancy symptoms. If you experience implantation bleeding at 13 DPO, it means that the fertilized egg has attached to the uterine wall. Implantation spotting is one of the most reliable early pregnancy symptoms.

When an egg implants in the endometrial lining, it causes a small amount of bleeding. It is often compared to the experience of implantation bleeding at 6–10 DPO.

However, this should be distinguished from implantation spotting that occurs around 14–16 DPO, which is common and caused by the egg burrowing into the lining, not by implantation.

Food Craving

You might start to crave certain foods at 13 DPO. This is because of the hormonal changes in your body. Increased levels of progesterone can make you feel hungrier than usual. You might also find that certain foods smell and taste different.

Other Possible Pregnancy Signs

There are other possible signs of pregnancy at 13 DPO. These can include:

  • a positive urine test
  • menstrual bleeding that is heavier or lasts longer than usual
  • fatigue or aching of your muscles, especially in the thighs and pelvic region
  • frequent urination
  • a bloated feeling
  • constipation or diarrhea

These symptoms may be caused by increased blood flow to the pelvic region and uterus. You might also notice veins on your thighs or breasts, which can be uncomfortable.

Undoubtedly, blood tests will detect pregnancy in most women by 13 DPO. However, it is interesting to note the other early pregnancy symptoms, which can alert you to the possibility of pregnancy.

13 DPO: No Symptoms

Some women experience no symptoms at 13 DPO and even later in pregnancy. This is common because every woman’s body processes hormones differently.

If you are not experiencing any symptoms, or if you are experiencing some but they are different than the ones listed above, this does not mean that you are not pregnant.

13 DPO BFN: Could You Still Be Pregnant?

You’re probably eagerly anticipating a positive pregnancy test result if you’ve been taking all the necessary steps to conceive. It’s vital to note that although a pregnancy test is 13 DPO is negative (often referred to as BFN or big fat negative), it’s still possible that you are pregnant.

While a negative result can be a little bit of a blow and take the wind out of your sails, it’s important to remember that it does not necessarily mean you’re not pregnant. There could be several reasons for this, ranging from misusing the test to an early miscarriage.

The first thing to remember is that not every pregnancy test is the same. Some are more sensitive than others, and they can show a positive result if you’re pregnant even when it’s too early for most tests to detect your pregnancy hormones. 

Every woman’s body processes hormones differently. If you are not experiencing any symptoms, or if you are experiencing some but they are different than the ones listed above, this does not mean that you are not pregnant. You may have ovulated later than usual during the menstrual cycle.

Stress levels can also cause a missed or delayed ovulation missed period, as can certain medications and medical conditions like polycystic ovary syndrome (PCOS). Other causes of the missed or delayed ovulation include things like heredity (your mother never had regular periods), weight changes (if you gain or lose weight suddenly), breastfeeding, stress, malnutrition, PCOS, thyroid condition, celiac disease, and more.

Wait until after 3 weeks to take an at-home pregnancy test. You can also make the first appointment with a doctor to get a first opinion about what is going on.
