Need advice

Nicole • Married for 3year, Together for 4years and a mommoe for 3years
Okay so I'm 20 years old and I have a three year old. My daughter's bio father has not been involved since I was pregnant but I got together with my best friend when she was two months old and he has been her daddy ever since when she was a year old we got married (November 22,2012 right after her birthday November 8 ) we had gotten pregnant and I lost the baby (November 1,2013) and we stopped trying after that . We think we are finally ready to have another baby any advice on ways to speed up this process. My husbands business is doing well ,we just paid off our home and I recently resigned my position as a pharmacy tech at the hospital I worked at to be home with my daughter and we really want another little ray of sunshine in our lives
