feeling baby kick low in vag

So this is a TMI post. But I'm a little worried. I'm 27 weeks and 5 days and I've been feeling a lot of pressure on my pelvic floor almost painful, for the past few days when I sit down. so a few minutes ago I was feeling weird down there and I put a finger in just to see what was going on and I can feel baby kick less than 2 inches into my vagina. I'm a ftm so idk if that's normal. But I've been carrying very low, I only started showing about 3 weeks ago and still just barely, but this seems a bit weird to me. Like it's like he's right there in the opening almost. Is this normal or should I call someone? btw I have a Drs appt on Thursday.1
