What do can i do

I need help i have a 6 year old. I have had 7 misscaregaes. And i am new to glow. I have never done this before. I have a thyroid issue. That makes me misscaregae and my husband doesn't want to have anymore kids because of the 7 that we have lost. Am i being selfish for wanting more kids i just want one more. I don't feel complete with just one kid. We have talked about having more but he's been unsure about having more. I love kids and when we got together 11 years ago we wanted to have 3 then it was 2 now its just my 6 year old. Who we love dearly. But our kid keeps asking when we're going to have a baby boy or girl help please
