Vaginal discharge after 7 days of coitus is caused by a variety of reasons, such as fast menstruation, inflammation, etc., and conception is not necessarily linked, so you can not judge by the amount of discharge to determine whether or not conception, conception or not should be judged by blood HCG. The amount of vaginal discharge in physiological conditions is related to the increase in estrogen levels, such as ovulation and premenstrual estrogen levels will increase significantly, under the influence of estrogen cervical glands secretion, so the secretion can increase; when a woman suffers from vaginitis, cervicitis, the stimulation of inflammation, the vaginal opening will also appear a large number of abnormal secretions. If you have intercourse for 7 days and successfully conceive, the level of estrogen in your body will increase, but the increase is not obvious, and the sensitivity of individuals to estrogen stimulation is different, so the amount of secretion varies greatly from individual to individual, so you can’t judge whether or not you’ve conceived by how much secretion you have. After conception, due to the formation of trophoblast cells, the level of HCG in the body can rise significantly, as early as 10 days after intercourse can be measured from the blood, which is the gold standard for judging conception. It is recommended that women go to the hospital in time for a clear examination.
