Recently, when a woman went to the hospital for a pregnancy check-up, she found that the previously calculated gestational age was not consistent with the individual development of the fetus. Therefore, women are very worried about whether the slow fetal development is caused by this. In fact, the reason for the inconsistency between gestational age and fetal development may be due to late implantation. Women want to know if there is a relationship between gestational age and late implantation?
Women who want to increase their chances of conception often choose to have sexual intercourse during the ovulation period. Ovulation period is composed of 14 days before the first day of their next menstrual cycle, followed by 5 days before and 4 days after. After the female egg is released, if it meets the sperm, it will combine to form a fertilized egg. However, it should be noted that male sperm can survive in the female body for two to three days. If the sperm swims to the fallopian tubes for a long time, it will first delay the meeting time between the sperm and the egg.
After sperm and egg combine, it usually takes three to five days to form a fertilized egg. If the fertilized egg takes five days to form, the time for it to be transported back to the uterine cavity through the fallopian tube will also be relatively prolonged. The fertilized egg takes about one to two days to return to the uterine cavity from the fallopian tube, and then stays in the uterine cavity for three to four days to prepare for implantation. The fertilized egg also takes about four to five days to complete implantation into the uterine mucosa.
If every step from the meeting of sperm and egg, to the union and formation of fertilized egg, to the movement of fertilized egg back to the uterine cavity and completion of implantation must be completed in the longest possible time, it will result in a longer time required for final implantation than normal, which will affect women's calculation of gestational age. Because many women calculate their gestational age based on the first day of their last menstrual period, accurate pregnancy cannot be determined, which can lead to errors in gestational age calculation.
