You might also want to contact your doctor and request that your levels be checked to make sure they are doubling. Also a ultrasound should be able to give you a little more information so I would maybe see if you could get one of those as well. But like everyone said bleeding can be normal in pregnancy. During my pregnancy I bled bright red blood worse than a flipping period for 5 weeks almost every day. My daughter is now almost 6 months and extremely healthy.
I agree with mj_mommy_manda if it is light pink or brown it is fine, bright red is when you should worry and if it is enough to fill a pad. Otherwise spotting after intercourse or an internal exam including a transverse u/s is completely normal..... Good Luck and have a Happy and healthy 9 months.
If the blood is dark brown or pink it should be fine.. if it is bright red is when you should worry. Also look out for cramping in your lower back or abdomen this could indicate the onset of a miscarriage.
Yes SOMETIMES its normal. But sometimes its not. You did what you should and went to the doctors. But still keep an eye out for anything else, And if you think you should see a doctor go see your doctor.
