It is possible to have internal ejaculation while taking the short-acting pill, which is composed mainly of estrogen and progestin, and should be taken every day. The pill is usually taken from the first day of menstruation or from the second to the fifth day of menstruation. During the first week of taking the pill, it is necessary to use other contraceptive measures for sex, but after a week, no other contraceptive measures are needed for sex, and internal ejaculation is possible. Short-acting contraceptive pills have a high success rate and can be taken for a long time. The main thing is to pay attention to taking them on time every day and not to miss them, and if you miss any, you have to take them within twelve hours.
