TTC after loss

My name is Julie and my husband and I lost our first son at 21 weeks gestation in April. We were told to wait a cycle or 2 to start trying again. I got pregnant so easily the first time (we got pregnant the 1st time not using contraception on our honeymoon!) and have a fear it won't be so easy the next time. We have tried to conceive now twice since our loss and I started my period today. I know that everyone has different experiences, but I'm curious to see how long it took other people to conceive after having a loss?
