Sex every day or Every other day

I’m curious to know how many of you got your BFP from sex every other day.

We have BDed every day for the last 4 days and last night he was unwell so we didn’t BD and my CM was dry so assumed I had ovulated but this morning I have a good amount of EWCM, so now I feel worried that we missed the chance last night and tonight will be too late. It’s hard to imagine sperm can really live for more than 24 hours!
