Sharp pain during sex 😕

I'm 36w4d and sex has been a bit uncomfortable since I hit exactly 36 weeks. It feels like he's poking something that shouldn't be there and it's like a sharp pain,even when being gentle. We have been having sex just about everyday since I've been pregnant and I've never felt this uncomfortable pain until now. It makes me not want sex anymore honestly. Im in a pregnancy group with midwives and never get checked down there but I'm going to bring this up at my appointment on Wednesday but until then does anyone know what could be the cause of this? Or has anyone gone through this?
