ttc #1

Dee
My husband and I stopped preventing about a year ago. We didnt start actively timing sex with opk until June 2016. I'm grateful that it appears I'm ovulating as the opks get super dark, but with wacky schedules we dont always get to bd during the optimum times. Should I be counting our ttc from when we stopped preventing or from when we started using opk kits and actively trying? I recently turned 34 so I don't want to waste time as friends of mine over 35 who have had issues ttc have warned me. Is it time talk to my obgyn about next steps? Suggestions? Advice?
