The vast majority of women will detect pregnancy by urine HCG at around 35 days of menopause, and by blood HCG at around 31 or 32 days of menopause. However, if a pregnancy is detected just after 60 days of menopause in clinical practice, it is likely that in the past when menstruation was regular, menstrual disorders have occurred recently due to stress, environmental changes, and emotional changes, causing ovulation to be pushed back. This is why it is only when the pregnancy is detected by laboratory tests at 60 days of menopause that the pregnancy is just discovered. It is advisable to have an ultrasound half a month to 20 days after the detection of pregnancy, to know the size of the gestational sac through ultrasound and finally to calculate the expected date of delivery.
