Has anybody had a BFP after a not-so-great BD session?

I am TTC and we BD'ed every day during my fertile period (yay). HOWEVER, on both peak days, my BF was tired (and probably bc it was 'on demand'); he did ejaculate but it was weak and likely a small volume... In other words suboptimal. 
I am a little bummed because 1) it's my first Clomid cycle, and 2) all our other BD sessions were fantastic! I realize it's a numbers game, but wondering, have any of you gotten pregnant when BD was not ideal? Thx!
