  • When the egg begins to ripen, you will produce more mucus, which you can see at the vaginal opening. It will be white, yellow or cloudy and you can feel it to be sticky.
  • You will have more mucus just before you ovulate, and it looks clear and slippery. If you hold it between your fingers, it stretches. This property is known as;Spinnbarkeit, a German word for fibrosity and stretchiness. This indicates your peak fertility days.
  • You will have about four days with slippery mucus, and then there will be a sudden fall in the flow. You will have a few dry days before your next period.

  • taking advice from a healthcare professional who has expert knowledge of using FAMs
  • checking ones body temperature, cervical mucus, menstrual cycle length, and other fertility signs every day
  • avoiding vaginal sex or using another form of birth control on ones most fertile days

Certain factors can affect fertility signals, such as:

  • illness, stress, and travel in different time zones
  • irregular periods
  • using hormonal contraception in the months before using FAMs

Additionally, the Standard Days Method âtracks your menstrual cycle for several months, in order to figure out if your cycle is always between 26 and 32 days long,” but if your cycle is longer or shorter, the method is rendered ineffective.

    If youâre planning on monitoring your cycle to discover the safest days to have sex in order to avoid pregnancy, consider using an app, such as Natural Cycles, which tracks your ovulation and fertility. According to Elina Berglund, the appâs chief technology officer and co-founder, roughly 85% of sexually active women who choose not to use any form of birth control will become pregnant within the year. âThis is why it is so important to, when it comes to birth control, increase choice, such that each woman finds something that suits her,â Berglund previously told Elite Daily. âThe risk is otherwise that she will not keep using it and then there is a high pregnancy risk.â

    How Do Ovulation And Pregnancy Work

    Ovulation occurs when a mature egg is released from an ovary. About once a month, an egg matures and is released into the fallopian tube. It then heads toward waiting sperm in the fallopian tubes and uterus.

    An egg is viable between 12 and 24 hours after it leaves the ovary. Sperm can stay alive up to five days after having sex. Implantation of an egg, which happens after fertilization, usually takes place 6 to12 days after ovulation.

    You can get pregnant immediately after your period. That can happen if you have sex toward the end of your cycle and are approaching your fertile window. On the other hand, the probability of getting pregnant right before your period is low.

    If youre tracking ovulation and wait 36 to 48 hours after ovulating, the chance youll conceive is low. The probability for pregnancy decreases the further in the month you are from ovulation.

    If pregnancy doesnt occur, the uterine lining will shed and your menstrual period will start.

    Ovulation occurs before 2 weeks of the period. So the women with short cycle generally ovulate within 5-6 days after period. Now if you have intercourse during your period, the sperm can stay alive in your vaginal canal for 5-6 days. Hence, there are probabilities of conceiving just after .5-6 days of your period. Its better to have safe sex at the time of period or after the period.

    The women with long menstrual cycle generally ovulate after 12-15 days of the period. If you also have a long cycle, then you can go for sex during your periods or just after you stop bleeding. The risk of getting pregnant is almost nonexistent at this time.

    However, we can say that there are low chances of conceiving while on period, but the likelihood is not null at all!
