Ladies! Question about ovulatiing and timing ?

I know this question might be pretty stupid, but I would rather be sure! I ovulated today (hopefully!) I have all the signs, and my OPK was positive about 36 hours ago. Me and my fiancee BD'd last night, and this morning. Is there less of a chance to conceive when you BD on the day of ovulation? I'm pretty sure there is MORE of a chance, but I have heard so many different theories that I don't know what to believe anymore. A little more info....I have a 29 day cycle, and my last period was Dec 26. I have a 14 day luteal phase as well. Thanks in advance for your help!
