Frustrated with my OPK “high fertility” days!

I feel a little frustrated, or maybe a little confused 🤷🏻‍♀️

I bought a clearblue advanced digital ovulation kit! This is my 5th day at high fertility (flashing smiley) and it could be this way until 9 days..

What I don’t understand while waiting for my solid smiley face is this: how can I have high fertility days for so many days in a row?! Sperm only live up to 5 days right? So now I’m on my 5th day. I can’t have sex everyday (we have every other day since the 9th) because of my husband and my schedule, and he’s leaving for business tomorrow night.

So..am I just out for this month if I don’t get a solid smiley in the next day?! Help! 😢
