I just need confirmation...

Re

I thought I had ovulated on CD 14.... Was on antibiotics the whole fertile window.. But on CD 19 I thought wat I feel was implantation pain on right side... Come to find out I actually ovulated that day... But heres wat I need confirmation of is if I had only bd on CD 13 and 14 do u think that I could still have concieved on cd19.. Going by that I would now only be 5 dpo instead of 10dpo????
