Rainbow baby after loss

Hi everyone, was just wanting to hear some of your stories of how soon you've been blessed with your rainbow babies after a loss? I had my son in April this year who sadly passed not long after he was born, I miss him so much but would like to try again as having a family is all I've ever dreamed off. Never to replace my firstborn though. My doctor says I'm ok to start trying again in a couple of weeks, I've started taking folic acid already to get my body ready for next time. Really hoping it won't take long to conceive.
