Ovulation

My husband an I had sex last night because my gynecologist told me to have sex every other day to increase the chance of getting pregnant. Also glow was showing yesterday 33% chance of getting pregnant. Today when I checked my mucus it was very clear, would it harm the sperm that's already inside to have sex again today? Because I've heard that new sperm kills the sperm that's already there?! While glow is showing that it's my ovulation today and that I'm having 22% chance of getting pregnant. What did you guys do
