How many days will birth control pills delay ovulation?

Taking emergency contraception is one of the contraceptive measures. Long-term use of emergency contraception will cause certain harm to women's bodies. Can cause menstrual irregularities. There are also some nausea side effects. Therefore, it is generally not recommended to use this type of contraceptive method frequently. So let's learn and understand whether taking birth control pills will delay ovulation.

Will taking birth control pills delay ovulation?

Under normal menstruation conditions, a girl's ovulation period is counted from the first day of the next menstruation, and the last 14 days are the ovulation period. The 5 days before and 4 days after the ovulation period are added together to form the ovulation period. This stage is very easy to fertilize. It mainly discharges the secondary coil oocyte, i.e. the egg. After this secondary coil oocyte enters the bilateral fallopian tubes, it undergoes the second meiotic division in the bilateral fallopian tubes. This breakdown occurs after fertilization, when the sperm nucleus enters the secondary oocyte. The result of the disintegration is a valid macrocell, the egg, and a polar body that cannot be fertilized. Pregnancy pills have side effects. Taking them may cause menstruation to be advanced or delayed. If the menstrual period changes, the ovulation period may also change.

How to calculate ovulation period

1. Cervical mucus method: In the hospital gynecology department, the ovulation period can be determined by checking the cervical mucus.

Cervical mucus elongation test method (this requires certain gynecological work experience to identify)

It is common sense that hormones increase during ovulation, and I think every woman knows it. This is because the cervix secretes a lot of cervical mucus during ovulation.

Testing method: First, wash your fingers thoroughly, open your legs, push your uterus with your lower abdomen, and then insert your fingers into the vagina. You will touch a small solid object, which is the cervical canal. If you are in the ovulation period, it will be filled with mucus. Take a little mucus and try to pull it. If it is the day of ovulation, the mucus can be pulled to 10-15 cm. If the mucus is placed on a coverslip of a microscope and observed after it dries, beautiful fern-like crystal images can be seen. The closer to ovulation, the larger and clearer the crystal image. The reason is that during ovulation, there is a lot of estrogen in the cervical mucus (we also call it secretion). The closer to ovulation, the more estrogen there is. On the day of ovulation, the estrogen reaches its peak. At this time, the secretion is the clearest and has the most wire drawing. Therefore, the fern-shaped forked image is the clearest. Not 100% of women can see the full screen cross.

2. Ovulation temperature method:

The so-called ovulation temperature refers to the body temperature when you wake up in the morning, when the body is quiet and the mood is calm. During the menstrual cycle, body temperature changes regularly during ovulation. The basic body temperature is lower after menstruation and in the follicular phase. After ovulation, the uterus and ovaries produce progesterone, which acts on the hypothalamic-pituitary immune nerve center, causing the body temperature to rise by 0.3-0.5℃, which lasts until 1-2 days before menstruation or the first day of menstruation, when the body temperature returns to its original level. Because human body temperature will change due to some reasons, so when measuring, you must have a normal life routine, the daily sleep quality should be maintained at more than 6 hours, and the daily measurement time should be basically the same. With the acceleration of the pace of life, work and rest time has become irregular, with an accuracy of about 60%.
