(1) the basal body temperature monitoring: the basal body temperature refers to the body temperature is not active in the morning, have been low in the early stage of the ovulation, after ovulation significantly higher about 0.2 ~ 0.5 ℃, the continued to menstruation is coming.
BBT is biphasic: this indicates that there is no biphasic pattern in ovulation, postmenopausal women or women who have their ovaries removed.
BBT is uniphasic: it suggests that there may be no ovulation. (2) cervical mucus monitoring: during the first half of the menstrual cycle, the cervix does not secrete mucus and the vulva is very dry. The cervix then secretes a small amount of sticky, opaque mucus. Before ovulation is about to occur, with the emergence of estrogen peak, cervical mucus becomes thin, transparent and clear, and the quantity also increases, known as reproductive mucus.
(3) ultrasonic imaging monitoring (B ultrasound) Generally, the follicle diameter was observed on the 10th day of the menstrual cycle, and the changes in follicle diameter were observed. The follicle diameter of the four days before ovulation increased by an average of about 3mm every day. The follicle matured about 17-25mm before ovulation, and the follicle disappeared after ovulation. (this method is reliable, but needs continuous monitoring, high cost).
(4) test paper method: at present, there are test paper for testing ovulation on the market, which can be bought for self-test. Place the test paper in your urine. If there are two red lines in the "small window" of the test paper, the egg will be released soon. This method requires several consecutive tests.
Among the above 4 methods, (1), (2) is relatively rough, (3), (4) accurately, but the price is more expensive.
