I went for blood pregnancy test last week my b-hcg was 8.57mlU and this week I started bleeding But not like my period it was not much and was too red and some tissue was coming out so I went for another blood test is now 67.7miu

The HCG levels indicate a positive Pregnancy. Have you had a check up with the doctor ? At times in early pregnancy there is a little bleeding at the time of placenta implantation. However other causes should be ruled out. Please visit your doctor.

Thanks for your answer but the did ultrasound it was negative and the bleeding has stopped. But the only symptoms am having is breast changes only is it normal?

there were some hormonal changes which might cause Breast changes. have you been asked to repeat the scan. How many weeks were you past your lmp

my last lmp was on December 17th, i only repeated the pregnancy test which was b-hcg 67.7 before I did this last test the 1st test was 8.57mlU before I started bleeding so I was instructed to do another hcg which is now 67.7mlU but the bleeding has stopped but the doctor said I should repeat the test in 3days time for the scanning I don't know if is because the pregnancy is still early or another thing.. But is my hcg increasing or reducing???

Your HCG is increasing and it will increase till about sixteen weeks of pregnancy.
