How Long After EWCM Will I Get A Positive OPK (And Why)?

Exact Answer: 1-5 days

Cervical mucus comes in various forms, depending on the timing of the menstrual cycle. Sometimes it’s dry, sometimes it’s sticky, and sometimes it is creamy. EWCM refers to the cervical mucus known as egg white cervical mucus.

It is given that name because it resembles the appearance of egg whites that are raw.

This kind of cervical mucus is produced when you are most fertile. This indicates that that is the right time to have intercourse if you wish to become pregnant. This is because the mucus is in a desirable consistency and pH for the transport of sperm.

OPK tests refer to ovulation predictor kits. These tests signify that ovulation is going to occur.

Egg white cervical mucus is a common indicator of ovulation. It tells a person that they are going to be ovulating very soon. This kind of cervical mucus is the most fertile as it has the highest chances of aiding in the movement of sperm up the vaginal canal and from the cervix to the uterus.

This is because the egg white cervical mucus has the consistency of stretchy raw egg whites that is suitable for the sperm to travel and survive in. In addition, this discharge helps maintain the pH of the normally acidic vaginal canal so the sperm can survive in it.

The absence of this kind of mucus will lower your chances of getting pregnant as the sperm will be unable to travel through and live in the vagina.

The time that one has to wait after EWCM to get a positive OPK result is 1-5 days.

OPK tests are kits that can be taken at home. These kits contain urine-based test strips. By detecting the LH hormone, these testing kits function and provide results that will help one decide when to try for a baby.

OPK tests detect the level of luteinizing hormone that is present in the urine. The level of LH hormone increases significantly right before ovulation. This is because the hormone stimulates the body to develop the egg and make it mature. This sudden increase in the level of LH hormone is known as the LH surge. The LH surge happens for 36 hours, after which the process of ovulation occurs.

There are two types of OPK tests: paper strips and digital monitors. The paper test strips are typically cheaper and are quite hard to read. Whereas, digital testing kits provide easy-to-read results that are more expensive and accurate.

Why Does It Take That Long To Get A Positive OPK After EWCM?

Egg white cervical mucus is triggered by the hormones that are released in the body. These hormones are also responsible for triggering the release of an egg from the ovaries, the process known as ovulation. In addition, these hormones also cause other changes such as the shift in the cervix, and your emotions.

The production of egg white cervical mucus is triggered by a hormone called Estrogen. So if the level of estrogen in the body is low, the body wouldn’t be able to produce enough fertile cervical mucus.

Moreover, these hormones also make the cervix open, softer, and shift a little higher.

After menstruation ends, the vaginal discharge changes from dry to sticky to creamy and lastly to EWCM, just before ovulation.

Ovulation is the process through which an ovary releases an egg. In a 28-day cycle, ovulation usually occurs on day 14. Ovulation is first set off by the follicle-stimulating hormone earlier in the menstrual cycle. It stimulates the maturation of the egg within an ovary. Then the LH hormone is produced for the release of the egg.

If the egg comes into contact with sperm, and if it is fertilized, then it will travel to the uterus. Here, the fertilized egg will implant itself and the person will become pregnant. However, if the egg is not fertilized, then it will disintegrate. This causes the lining of the uterus which was prepared for a pregnancy, to break down and shed. This is menstruation.

The reason why it takes that long for the positive OPK result after EWCM is because hormones such as LH and estrogen need to be released in order for ovulation to start, and it usually takes 1-5 days before this can be achieved.

Conclusion

Thus we can understand that you can get a positive OPK result on your test anywhere from 1 to 5 days after you first see egg white cervical mucus. This waiting window differs from person to person, and often depends on the timing and length of the menstrual cycle.

In addition to OPK tests, people often use basal body temperature (BBT) tracking methods to identify the time at which you will be ovulating. The basal body temperature has a tendency to rise during ovulation. Your BBT typically increases by 0.5°F or 1°F after the appearance of EWCM. Tracking your ovulation helps you decide when to try getting pregnant.
