Trying for a baby girl

Brandy
Hello I'm brandy I'm 20 and trying for my second child. I already have a 2 year old boy who is my world and I want to have another one hopefully a girl. I got pregnant or had pregnancy symptoms when I was on the mirena and unfortunately lost it when my birth control fell out. I wasn't trying when I was on my bc but after it was all said and done I decided to try for my second and last child lol. I have been trying for about 3 weeks now and had my period last week. My first child was not planned so hopefully it won't take me long. :) thank you
