Signs of ovulation or what?!

So according to this app I’m ovulating this week. My bf and I have been BD all week! But yesterday I noticed sharp pain during intercourse in my lower abdomen and it feels like so much pressure is “down there” it hurts to walk and sit. I originally thought oh im constipated but that’s not the case :(. Just kinda curious if anyone else can relate to this, because I’ve never had this type of pain. Of course my bf just automatically assumes I’m pregnant lol. He’s so excited for something that hasn’t happened yet but I love it lol
