Women have intercourse when their period has just ended, but it leads to pregnancy, which is generally to consider two situations: 1, the woman’s period is particularly long, and the menstrual cycle is relatively short. So when the period has just ended, it has already reached the time of ovulation, so intercourse can lead to pregnancy.2. Consider the unexpected pregnancy manifestation caused by the stimulation of intercourse, leading to early ovulation, so there is no absolute safe period. Since you’re already pregnant, if you don’t have the requirement to have children, check the ultrasound to confirm the diagnosis of intrauterine pregnancy at around 45-50 days after menopause. Also consider whether to take mifepristone and misoprostol to carry out a medication abortion, or direct abortion to terminate the pregnancy.
