TTC after 20 week loss

Back in January I lost my first pregnancy at 20 weeks. I got pregnant with her very quickly, only on the first month of trying. 
I am ttc again, now on 3rd month and af due today and got bfn. I know 3 months isn't very long for ttc and I was very lucky before to get pregnant so quickly before.
I was just wondering if there was anyone out there who has had a late loss like me and how many cycles if took you to get pregnant after?
