last pill of clomid!

Jh
So I'm on day 7 and will taking my last pill tonight. I haven't experienced any side effects and I think it's because I've been only taking it before bed..which has been nice. 
My only question now that I'm almost done with my first cycle (and hopefully last) is..when should my SO & I BD? He wants to asap and I'm not certain if we should wait and save his sperm or not? 
Any advice would be awesome! 
Also...I think I'll get some mucinex tomorrow to help out too! ;)
