Can I be pregnant if my period hasn’t left in ten days? It is possible. If you usually have normal periods and have sex without using proper contraception, you can get pregnant. You can take a urine pregnancy test or blood test for HCG to see if it is elevated. Of course, you can also do an ultrasound to see if the pregnancy is intrauterine or ectopic. If it is a preeclampsia, there will be vaginal bleeding after menopause, and an ectopic pregnancy will also have irregular vaginal bleeding, so if the blood HCG is not elevated, pregnancy can be ruled out. Do ultrasound to see if there is any mass in the uterine adnexa to exclude organic lesions. If there is no abnormality in the ultrasound examination, it is endocrine disorders, which need to regulate menstruation and stop bleeding treatment.
