I gave birth to a stillborn

Hi I gave birth to a stillborn on 3-22-16 ,yes I'm grieving still in the process of grief but I know I want another child. It took me nd my husband 4 years to get pregnant he has a low sperm count that's what makes this hurt even more . Our baby was born at 25 weeks. My question is how soon did some of you other women who may have experience this try getting pregnant again. Thank you
