I think we can feel baby’s head near my Vagina

So I have a lot of mild cramping and small movements near my pelvis bone. I took a nice warm shower because the pressure so much I was laying down and I have a huge lump near my vagina lips, it’s hard that is very new because we had sex yesterday and I lost pieces of my mucus plug during... my contractions are far from each other and now very calm after the shower but I have so much pressure I’m sitting on my yoga ball and waiting for contractions to start back up because I’m just mild cramping.

This is my second baby, but my first was a fast labor and I remember most of it but not anything like this. He has dropped a lot from yesterday morning....

Has this happened to anyone? I’m considered petite even tho I’m a bigger now.
