Hi, I too had bleeding this past weekend, for me it was bright red fresh blood. i am currently 12 weeks pregnant. I took myself to the hospital and the doctor i saw told me that it is not uncommon for women to experience thier first second and sometimes third periods when they are pregnant and still continue to have normal healthy pregnancies and babies. You say the bleeding has stopped thats a good sign, i would suggest you mention it to your doctor next time you are there so they can make a note of it, or if it starts again and as the doctor told me if its its more the a teaspoon full see a doc asap.
good luck, wishing you a happy and healthy pregnancy with lots of sticky vibes.
Mel
