Wild baby movements ?

I’ll be 40 weeks in just one day. Last night and today my baby has been going crazy with movement like really hard movements. I know he’s head down, but isn’t baby suppose to have less movements before labor not a huge increase? These movements are actually really uncomfortable. Sometimes I feel him push down on my cervix, which create sharp pain, sometimes I feel him push down on my butt, or he will kick my ribs hard. I feel he’s low because how much pressure I’m having. Anyone else experience this?
