How long until sperm is back?

OK so this is going to be tmi but...

My hubby and I had an awesome baby free night last night and had sex like crazy. Within a time span of like 4 hours he came inside me 5 times. This is my fertile week but glow says today is most important day to have sex.

So my question is how long until his swimmers are back and we can BD again? Or will it hurt or chances of conceiving if we continue our marathon today? Would it be better if we waited a day even though today is best day?

I want to have another baby but this BDing thing is kinda fun you know ;)
