Do we need to BD again today?

I got a positive opk yesterday morning, we BD on Thursday, Saturday and yesterday.

I tested opk this morning just to see and it's still dark positive line. I'm also have the ovulation pain on my left side.

So my question is do we need to BD again today if we've done it three times already? Is that enough to possibly get pregnant? Sperm live for a few days right?

I came down with a fever last night and feeling horribly sick today so not really in the mood for sexy time 🤒

Thanks for your input.
