i started bleeding yesterday and im pregnant, woke up today still bleeding with mild tummy cramps. i went for an internal scan and they said i was 5 weeks, the sac is in the right place and my cervix are fine. I have to go back in 2 weeks for another scan, i have just passed a blood clot and the cramps have now stopped, but i noticed something that looked like a bit of tissue it was white and about 1cm long, have i miscarried?
