Hello, I Have Been with my boyfriend for over 14 months now and i am getting really broody as i have grown up with 5 nephews they are now embetween the ages of 8-15 months. My boyfriend has one child who he doesn't get to see but because of that he won't have a child with me. I also have the implant but he said i can't get it out because he doesn't want me to get pregnant. I really want a baby and have thought about it for a long time now.
