What’s this feeling? TMI

So I’ve felt pressure on my pelvis before but for the last few days I’ve been getting this weird feeling in my cervix I think. The only way I can describe it is when your having sex and you feel the penis pushing onto your cervix opening. Idk of that makes sense lol. This is my first pregnancy so I’m not really sure what sensations mean what yet. Also today I noticed that my baby’s bottom and kicks feel about two to three fingers width lower than usual. Anyone else?
