It is recommended to start testing on the tenth day of menstruation and test once a day with ovulation test strips. If you find that the test is gradually getting stronger, you should increase the frequency of the test, preferably every 4 hours, and try to test until you get a strong positive, and catch the moment when the strong positive turns weak. If you find that the egg is about to break out of its shell, you have to hurry up! You must ovulate within 24 hours, and you should not drink water 2 hours before taking the ovulation test. Do not use the morning urine test, it is best to test at 10-20 o’clock. After the strong positive turns weak, continue to test the ovulation test, do not be afraid to waste the ovulation test paper, until the test is negative, then you can rest for a few days, and start to test the ovulation test paper every day until 10 days after ovulation, if you find a strong positive, the hope of good pregnancy will be greater, you can use the early pregnancy test paper to test, generally at this time the early pregnancy test paper is weak positive. If you need to do ultrasound monitoring, it is best to go to the hospital to do ultrasound immediately when the ovulation test is positive. How to use: Step 1: Menstrual cycle The number of days between the first day of your period and the day before your next period is a menstrual cycle, usually 26 to 35 days. Prepare a menstrual cycle chart for yourself. Record the first day of your period each month, and between the two times you will have a menstrual cycle, which you will need to record for three or four months to accurately calculate your menstrual cycle. Ovulation day: It takes one or two days for a mature egg to travel from the ovary through the fallopian tube to the uterus, but this 48-hour period seems to be very short. It usually occurs about 14 days before the next menstrual period. Easy Pregnancy Period: This 48-hour period is definitely a high-risk period because the sperm can survive for about 72 hours after entering the uterus and will lurk in the uterus for three days to capture the newly emerged egg at any time. Step 2: How to lock in the fertile period The key is to find the days in the middle of menstruation. It’s not complicated, just do kindergarten level arithmetic problems, just subtract 17 from the shortest cycle and 11 from the longest cycle and you will have the answer. For example, if the menstrual cycle is 30-32 days, use 30-17 = 12, 32-11 = 21, and the danger period is 13-21 days. Mark these days with big red circles. Test with ovulation test paper during this period and a positive reaction will indicate that you are nearing the high-risk pregnancy-prone period. Step 3: How to do it exactly Follow the appeal method and test for at least 3 months to get a good grasp of the pattern of your cycle before planning your pregnancy. In other words, you should test with ovulation test paper every day before having intercourse during the risk period, and a positive reaction will indicate that you are approaching the high-risk pregnancy stage. Once you have an accurate picture of your biological cycle, then start to act. Just schedule intimate exercise properly 3 days before and 3 days after the ovulation day.
