Timing and TTC....did we do it right?

Hello- My DH and I are fairly new to TTC. This is our 2nd month on clomid (50mg days 5-9). Here's our situation this month. I purchased preseed and have began using it since I haven't been seeing any EWCM while on the clomid. Two nights ago we used it for the first time and BD'ed. Then yesterday afternoon I got a smiley face on my OPK (woohoo! Day 17). We BD'ed again last night and again used preseed. I'm guessing I will ovulate sometime today since yesterday was my positive. We will BD again today but should we continue for the next couple days as well? Has our timing been good so far with BD'ing the day before the positive OPK and the day of the positive OPK? Just nervous....thank you for any advice. Good luck to all others who are in my shoes as well.... :)
