Hi everyone I'm new to this and wanted some advice, I've been trying to conceive for 2 years now and I do the OPK pretty much every month. I did an OPK on cd16 and it was quite light so we DTD that night and I did another OPK on CD17 and it was positive, I also got the dull aching pain in the left hand side of my abdomen does this mean I will have ovulated this day? We also DTD that night too so I'm hoping I will have conceived this month. My question is do you think I will have ovulated on CD17 or should we have also DTD on CD18 as well? Thanks
