TTC after a miscarriage ,

Hi guys, did anyone had a hard time getting pregnant after doing a D&C, last time when we tried to conceive i got pregnant right away on out first cycle, but unfortunately it ended up in a miscarriage when i was 15 weeks, I had a D&C after that, we wanted to wait for awhile before we try again, so after almost around 6 months we are trying again now and this is our second cycle trying and, still no results,

Did anyone had the same issue like hard to get pregnant after a D&C ,

Please help,
