We went back to the MD yesterday and all is OK now. He did an ultrasound again and this time I could see the baby and it's heart beat (it is too little to hear it yet). The MD told us that everything is fine now and that the bleeding was from where the amniotic sac is growing across my uterus and causing small tears. It is nothing to worry about at all. After seeing the baby and it's heart beat I am soooo excited and can not wait until it is here in my arms!!!!
