Bright red bleeding at 13 weeks but ok...

Tiffany
I had a huge gush of bright red blood at almost 13 weeks and cramping. My doctor told me to rest. It stopped. They did 3 ultrasounds and no placenta privia, cervix looks good, baby is jumping around.. She said after a week I can slowly go back to normal.. Has this happened to anyone else? It was so scary and we are still nervous...
