Ttc after chemical pregnancy!

We just started ttc back in november around thanksgiving time. Around dec 17th i started feeling a little funny (sleepy, picky eating) so i decided to take a pregnancy test. When i did it was positive, went to the dr got blood work and after being told my hcg was too low, i started spotting on the 23rd of december. My doctor said it was an early miscarriage ( my heart is still broken) unfortunately im on my first cycle after the cp. Well, i want to know how long after a chemical pregnancy did it take any of you ladies to get pregnant?
