Conceive time

Hi does anyone know if the "try for a year before seeing a Dr" still applies after miscarriage? I miscarried November, Im not counting December as a ttc month but if I count jan 2018-jan 2019 do I have to add more months to that ttc time like a year & a half ttc before seeing my dr? since my body was thrown off track after miscarriage not sure if it needs more time to ttc, I feel like I'm not making sense. I hope someone understands my question..
