Serious Question Here

My SO and I have been trying to get pregnant. This is our first time ever trying. We Baby danced three days ago, which was the second day of my blink smile face on the Digital opk I took, which was high fertility. Today, I got the solid smile, which means it is my ovulation day. So we baby danced again. When we first had sex a few days ago, there was a lot of cum. It was everywhere! Sliding off my legs and all. Today, my SO said he finished inside me but I don't feel any cum sliding out. It doesn't feel all that wet. Is this because we had sex a few days ago and the sperm count is lower? I am scared he didn't actually cum. He says he did, but I feel like I should feel it. We have always done the pull out method for our contraception method so I am not used to what it is like with cum inside me!
