Please let there be hope

Okay so last time my husband and I had sex was three days ago, I had my FIRST EVER peak reading today and a dip in bbt!! We’re going to have sex today but we’ve been busy, and I’m actually really worried that it may be too late as I think his swimmers might be slow. Any words of encouragement? I’m freaking myself out because I actually will ovulate and this could be it, I’m worried something could go wrong.
