Trying to concieve Baby dancing ?'s?

Is it ok to BD everyday (example: 3days before day of O and day after) around ovulation? I want to make sure I get in all the BD-ing I can but I don't want to chance a low sperm count. I've been doing my OPK for 4 days now.. and this morning it was almost as dark as the right line, so O is probably going to happen within the next 24-48 hours and we have already BD-ed Yesterday and the day before...should we again tonight- or wait til tomorrow?
