17 DPO: Late Period and Pregnancy Symptoms 17 Days Past Ovulation

It’s possible for tests to detect pregnancy before a woman misses her period, but you might notice symptoms even earlier than this. The first symptom of pregnancy is usually a missed period, which happens around 15–17 DPO. Along with a late period, pregnancy symptoms 17 days past ovulation include implantation bleeding, cramps, breast and nipple tenderness, and mood changes. Monitoring your ovulation helps maximize your chances of getting pregnant naturally.

17 DPO: symptoms of early pregnancy 

According to the National Institute of Health, signs and symptoms of pregnancy 17 DPO include:

Tender breasts

Your breasts will probably become a bit more tender in the early months of pregnancy. As early as two weeks after getting pregnant, your hormones undergo a lot of changes, making your breasts feel tender and tingly.

Sensitive nipples

During early pregnancy, your nipples may also become sore. Sensitive nipples are a sign that your body is preparing for breastfeeding. The area around the nipples also starts to darken.

Heavy or full breasts

Some women notice that their breasts feel fuller and heavier in the early months of pregnancy. The two hormones estrogen and progesterone increase the number and size of ducts and milk glands in the breasts. This makes them retain water, swell, and feel heavy and full.

Sensitive breasts

Increased hormone levels during pregnancy increase blood flow. This leads to changes in your breast tissue, making your breasts feel more sensitive than usual and sometimes sore and tingly. 

Increased smell sensitivity

Many pregnant women experience a change in their sense of smell during the early months of pregnancy. During the first trimester, the smells of some foods, drinks, and toiletries (like perfumes and lotions) become less (or more) appealing. This shift is due to hormonal changes, most notably, the hormones estrogen and human chorionic gonadotropin (hCG).

17 DPO: pregnant or late period?

Although pregnant women experience multiple symptoms at 17 DPO, it is quite common to get multiple big fat negatives (BFNs) before the big fat positive (BFP) result. Some women start experiencing pregnancy symptoms well before they get a BFP. Remember too that every woman’s cycle is different. Even if you’re getting a BFN after 17 DPO, you might still be pregnant. Here are some of the symptoms pregnant women might experience at 17 DPO.


Some women experience throbbing and pulsating headaches in their early months of pregnancy, which may be related to changes in hormone levels. 

Mood swings

Stress and mood swings are common symptoms experienced by many women in the early stages of pregnancy, even if they’re still seeing BFNs on pregnancy tests at 17 DPO. Many women experience heightened emotions or crying spells. The tremendous changes in hormone levels are the most likely reason for these changes in mood.


Women tend to experience a lot of cramping in the early stages of pregnancy. These cramps happen when the fertilized egg is implanting in the uterus. Most women describe implantation pain as dull, intermittent cramping in their lower back or lower stomach. 


Even if you’re pregnant, you might notice some light bleeding or spotting during the first few days of your expected period. This can also happen due to implantation, when the egg attaches to the uterine wall.

Not feeling pregnant

The frequency and severity of symptoms in every woman are different. Most pregnancy symptoms start around the fourth week of pregnancy. More obvious physical changes, such as weight gain, acne, and breast changes, tend to occur between weeks 9 and 11. By the second trimester, many of the more intense pregnancy symptoms start to go away, but others will stick around until the moment of delivery. On the other hand, some women don’t feel any symptoms in their early days of pregnancy and never suspect that they’re pregnant. 

17 DPO hCG levels: what will your pregnancy test show? 

Human chorionic gonadotropin, or hCG, is the hormone released by the placenta when you’re pregnant. It is usually detectable in your blood within a few days after implantation. If hCG is present in the blood, then the pregnancy test will be positive. Urine pregnancy tests typically show a positive result starting at 14–15 days after implantation. At 17 DPO, the average hCG level is expected to be 132 mIU/ml, with a typical range of 17–429 mIU/ml.

Normal hCG values in pregnancy

  • Blood hCG less than 5 mIU/ml indicates a negative result. You’re not pregnant.
  • Blood hCG between 5 and 25 mIU/ml is an equivocal result. Repeat the test in few days.
  • Blood hCG higher than 25 mIU/ml indicates positive result. You are pregnant! 

How many days past ovulation is enough to know you’re pregnant?

A pregnancy test can be positive before a woman misses her period, but some women start experiencing symptoms earlier than this. The first sign of pregnancy is often a missed period, which happens around 15 DPO. If you decide to take a pregnancy test as early as 7 DPO and you get a negative result, take it again in 2–3 days. 

The simple answer to the question “how many days past ovulation is enough to know you’re pregnant?” is between 7 and 10.

17 DPO is a significant milestone, especially for women who are trying to get pregnant. However, a late period is not necessarily a sign of being pregnant. There’s also always the chance of a false-negative if you take the test too early. Some women start experiencing symptoms of pregnancy as soon as 8 DPO, after the fertilized egg has implanted in the lining of the uterus.

Monitoring your fertile window is an important part of your sex life, especially if you’re trying to get pregnant.  Once you ovulate, there is a small window of opportunity — roughly 12 to 24 hours — before your egg degenerates. Fertilization can take place in this window. If the egg is fertilized and implantation has taken place, you can expect a pregnancy test at 17 DPO to give a positive result.
