A sudden increase in discharge does not necessarily mean that you are pregnant, as a persistent increase in progesterone prior to menstruation can also cause an increase in white discharge. If possible, pregnancy can be determined by testing, for example, by buying a pregnancy test about 12 days after intercourse, to rule out the possibility of conception. Even if there is a pathological condition, there is an increase in the amount of leukorrhea, because it is accompanied by vaginal inflammation, an imbalance in the environment of the vaginal flora, which also causes an increase in the amount of discharge. Since it is not scientific to judge by the discharge at this time, it is better to take measurements at this time. In the preparation for pregnancy as far as possible to choose the ovulation period for intercourse, so as to increase the chances of conception, even if you do not need to prepare for pregnancy contraception, as far as possible in any period of intercourse should be taken in the form of condoms for contraception, so as to avoid changes in the ovulation period.
