If you have intercourse just after your period and the test reveals that you are pregnant, this only indicates early ovulation. There is no adverse effect on the development of the gestational sac, so regular checkups in the future will be sufficient. However, the expected date of labor may be a few days earlier because of early ovulation. Also, when you do a pregnancy test, you may find that your baby is developing slightly larger than the gestational week calculated according to your last menstrual period. This is all due to early ovulation and is not abnormal, so there is no need to be nervous or anxious. It is sufficient to follow the maternity check-up program as specified in the Maternal and Child Health Handbook and have regular check-ups throughout the pregnancy. A woman’s ovulation period can be affected by many factors, such as changes in routine and living environment, either earlier or later. However, the quality of the eggs is not usually affected, so the quality of the fertilized eggs will not be affected.
