I am 6 weeks and 5 days and my OB told me that the baby implanted low in my uterus. He said there is a 50% chance that I can miscarry and a 50% chance that I will carry to term. I have had heavy bleeding 3 different times with clots but they did an ultrasound and said everything looks fine they are just worried on how low the baby is. Anyone else have their baby implant low?
