5 weeks of pregnancy is 35 days, 1 week is 7 days, 5 weeks it is 35 days. Pregnancy is calculated according to the time when the last menstrual period starts, not according to the time of intercourse. Therefore, if you are pregnant at 35 days, you should wait for 5 or 7 days before going to the hospital for an ultrasound to determine if there is a gestational sac in the uterine cavity. Not all pregnancies are intrauterine, but there is also a chance of ectopic pregnancy. During the observation period, if there is abdominal pain, including bleeding, it is necessary to go to the hospital to check progesterone, HCG and ultrasound to ensure the stability of the fetus and, if necessary, to take oral medication to preserve the fetus. Similarly, if the pregnancy needs to be terminated, it should be done at around 42 days, i.e. around 6-7 weeks, if possible, when a medical abortion or an abortion can be performed.
