When a woman's menstruation comes, the basal body temperature is low; after ovulation, the basal body temperature will turn to high temperature. In general, women have a lower rate of fertilization 24 hours after ovulation; however, men's sperm can survive in a woman's uterus for up to about 5 days. Therefore, women should have intercourse before the basal body temperature rises and when they are close to the ovulation period, and can have sex every two days, which can increase the probability of fertilization; if the basal body temperature reaches a high temperature before intercourse, then the probability of pregnancy has been lowered.
These types are mostly characterized by "fat", and are often prone to obesity, acne, thick hair, and irregular menstruation. It is manifested in the basal body temperature: the high temperature period is short, and the severe one may be frequent low temperature. Women with this condition usually have familial genetic diabetes, such as pregnancy and childbirth, they belong to the high-risk group of gestational diabetes.
People with poor ovarian function usually shorten the basal body temperature cycle. The original 28 days may gradually become 24 days or 22 days, and the high temperature period will be shortened accordingly.
If the prolactin is high, the high temperature period of the basal body temperature will be shortened, and the quality of the eggs will be poor, so it is not easy to get pregnant or easy to miscarry. Therefore, it is important that you use a smart bbt thermometer to keep track of your body condition.
The basal body temperature is a safe period (not easy to get pregnant) in a high temperature period, and a dangerous period in a low temperature period, but there will be individual differences in the low temperature period. For example, for young girls, their ovarian function is good and their secretions are large, the risk period is correspondingly longer, and the probability of sperm surviving in the uterus will be relatively high. Therefore, it is likely to start 5 days before ovulation and must be regarded as a dangerous period.
If couples often choose to have sex during the dangerous period, but there is no sign of pregnancy, then they must go to the hospital to find out the reason, whether it is the lack of sperm count in men, or the failure of the fallopian tubes in women, or there are other reasons.
