Miscarriage and conceiving again

Shelby • Mommy to a sweet little girl 🌸. •September 8, 2017 👶🏽💕• Baby #2 October 2021
I miscarried in September and had my D&C in the beginning of October, and it left me heartbroken. I stayed locked away from everybody for a few weeks and just cried. Depression isn't the word for how I was feeling. I wanted that baby so bad, more than anything. 9 weeks and I was already buy little gender neutral outfits, bottles, pacifiers, toys, playpen, and other baby furniture. I see that stuff every day and I still hurt badly over that loss, but I want to try again. I talked to my friends and family about the topic and my mother and mother in law are happy that I want to try again, and are ready for me to when I am, but A couple of people who I've opened up to about trying again has completely shot me down and said i should "wait." 
Am I wrong for wanting to try again? Is it "too" soon? Am I being unfair to the child I lost? I'm completely shattered at this point...
