Changes in LH after pregnancy

If the normal menstrual cycle is regular every 28 days, ovulation should be on the 14th day before the next menarche. The 4 days before ovulation and the 5 days after ovulation are called the ovulation period. After ovulation, the body produces progesterone, which will be metabolized as LH. The increase in progesterone levels will cause the body temperature to rise by 0.3~0.5 degrees Celsius. The body temperature changes in a phase, so we can tell whether there is ovulation. If you get pregnant after ovulation, the LH level will continue to rise and continue to rise for 18 days, which means the possibility of pregnancy is relatively high. If it continues to rise for 21 days, the possibility of pregnancy is even greater. In clinical medicine, ovulation test strips can be used to detect whether it is the ovulation period, and early pregnancy tests can be used to detect whether you are pregnant.

Before ovulation, the ovulation test paper will show a strong positive result. After the ovulation period, the ovulation test paper gradually turns negative. If pregnancy is successful, the ovulation test paper will become weak positive again. Since the α subunit of LH detected by the ovulation test strip has the same structure as the α subunit of Hcg, a crossover phenomenon will occur. After the ovulation period has passed, do not use ovulation test strips, you should switch to early pregnancy test strips. The early pregnancy test strip checks the β subunit of Hcg, which is unique to Hcg and eliminates the influence of LH, making the result more accurate.

During pregnancy, the body's progesterone level increases, and the ovulation test paper is always positive. This situation does exist. If it does not affect the fetus, then there is no need for treatment. It is not likely to have any impact on the body. Just observe and see if it is appropriate. You need to go to the hospital for a detailed examination. If the fetal examination is normal, then there is no need for treatment. It will not have any impact on the human body. Just observe and check first. It will not have a big impact on the human body.

Normally, after ovulation, if the couple becomes pregnant, the ovaries will stop ovulating and developing. Progesterone and estrogen levels will be very low. Estrogen and oestrogen levels will rise. If the test paper continues to be positive after ovulation. It should not be a sign of pregnancy. It is best to do a blood test to diagnose whether it is the ovulation period.
