Miscarriage questions .

New to this group ..congrats to all the expecting ladies . I recently had a miscarriage Aug.7th and a few days later I decided to download this ovulating app . My fiancé and I are newly engaged and have been trying to get pregnant for Months now so the miscarriage was a real let down for us . My highest day of fertility is tomorrow and I just pray that I get pregnant . We are getting married next year June 2020 and would love for our baby to be n the wedding . So, I have a question ladies how soon can you get pregnant after having a miscarriage?.. I looked online and it said 2 weeks is that true ?
