Low implantation

Crystal • I’m ttc my 5th child at age 31
I went to the doctors after finding out I was pregnant. They told me that according to my ultrasound this was not a "normal" pregnancy and that I should get a DNC bc the baby implanted very low in my uterus. I refused the DNC and went for another ultrasound a few days later. The baby had a strong heartbeat and everything looked great according to the tech besides the fact that the baby implanted lower than they would like. Anyone else have this problem and still have a healthy pregnancy? I'm so afraid to m/c because I've been through it before and its something i never want to go through again!
