When is the right time to have another baby?

I had my sweet Bailey Rae three months ago and she passed at birth due to thanatophoric dysplasia 💔 it's been very hard. It broke me and my significant other up. We no longer talk. I want another baby so bad. I wanted Bailey so bad and wish I could just have her. I still would love to have another and be pregnant again. When is the right time? I am not with anyone but why do I keep feeling this way of strongly wanting to be pregnant again?? Any advice pleasee
