Bleeding after 3 weeks of missed period indicates what?

Question
Hello doctor,
I usually have my period on the 26th of the month, lasting 5 days. However, as of today, my period is 3 weeks late. When my period is 4 days late (ie, day 30), I took a pregnancy test and it showed a dark line, a little later showed a faint line, the longer I left it, the darker the color. I tried 3 sticks, 3 sticks still have the same results. On the 9th day, she had abdominal pain, little blood after going to the toilet, bright red. On the 13th, I went for an ultrasound and the doctor said the mucosa was thin, not like pregnancy, like about to ovulate. After the ultrasound, I bought a pregnancy test, the 2nd line still shows up after 5 minutes, very faint. That night, I had bleeding, blood clots but little, there was mucus, the amount of blood was as much as menstruation, bright red, pain in the lower abdomen, I also had blood in my bowel movements. The pain lasts a few hours and then goes away. Doctor, tell me, what does bleeding after 3 weeks of delay indicate?

Hello,
With the question "What does bleeding after 3 weeks of period delay?", the doctor would like to answer as follows:
Current methods of detecting pregnancy are basically based on diagnostic principles diagnostic imaging such as transducer ultrasound, abdominal ultrasound or based on hormone changes in the female body. Using a pregnancy test is always the first choice of women due to its convenience as well as instant results.
However, there is still another method for more accurate fetal detection results that is to take a blood test. This is essentially a test to check the level of Beta-Hcg present in the mother's blood or urine. The hCG hormone appears soon after the egg is fertilized and implanted in the lining of the uterus and the concentration reaches the maximum when the fetus is 2.5 months old and stabilizes until delivery. Therefore, the presence of hCG hormone in the blood is the clearest evidence of pregnancy. If the HCG level is negative then the symptoms you describe are just signs of menstrual pain. In addition, you should have a transvaginal ultrasound to rule out an ectopic pregnancy.
If you still have questions about bleeding after a missed period, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
