Ovulation test strips instantly show positive results for early pregnancy

Ovulation test strips are a treasure for women who are preparing for pregnancy. To put it simply, ovulation test strips are used to detect the ovulation period. Can ovulation test strips also be used to detect whether you are pregnant? If the ovulation test paper shows a strong positive, does it mean that you are pregnant?

1. Ovulation test strips and early pregnancy test strips

The ovulation test strips mainly measure the progesterone (LH) in women's bodies; the early pregnancy test strips are used to test the early stages of pregnancy, which mainly test the human chorionic gonadotropin (HCG) produced by the trophoblast cells of the embryo. HCG has two chains, α and β. The structure of the α chain is similar to that of LH and fsh, and it is easy to produce cross-reactions. Therefore, β is generally used as the standard for judging whether pregnancy is present in medicine.

Because HCG and LH cross each other, sometimes ovulation test strips can also reflect the early stages of pregnancy. Because today's early pregnancy test strips almost all detect βHCG, and the β component in HCG is much smaller than α. When βHCG is only 50-100, αHCG has usually reached one or two thousand or three thousand. The early pregnancy test paper is determined by βHCG, and the cross-reaction is determined by αHCG, so the ovulation test paper will show a positive result earlier than the early pregnancy test paper.

However, the absence of a weak positive result on the ovulation test paper does not mean that you are not pregnant, because cross-reaction is not certain. A positive ovulation test does not mean that you are pregnant, because it may be that your LH has not completely withdrawn, or it may be a cross-reaction with FSH. What's more, even if it is really a cross-reaction of αHCG, it does not indicate pregnancy. If αHCG is present but βHCG does not catch up, it will be of no practical significance.

Therefore, a strong positive result on the ovulation test paper may or may not indicate pregnancy. It is recommended to use an early pregnancy test paper for testing.

2. Ovulation test strips predict and analyze the "best time" for sexual intercourse

Ovulation test strips are only useful when you are not pregnant, and are used to detect the ovulation period. Generally speaking, it is indeed easier to get pregnant if you have sex after the ovulation test paper shows a positive result. After the ovulation test paper shows a strong positive, ovulation will occur within 24 to 48 hours, and the probability of pregnancy during this period is high.

Among them, having sex 2 to 3 hours before the ovulation test paper weakens is most likely to "help pregnancy." However, it must be noted that the duration of strong yang is different for each person. Some people ovulate 6 hours after strong erection, while others may have strong erection for 2 or 3 days. Therefore, it is still necessary to judge a woman's ovulation period according to the duration of her own strong erection and arrange sexual intercourse.

Now the answer is very clear. The main function of the ovulation test paper is to detect the ovulation period. Although it does not rule out the possibility that the ovulation test paper is positive, it is recommended to use the early pregnancy test paper for more accurate detection.
