38weeks6days keep having shooting pains / twinges in my vagina and pressure in my bum

🤷🏻‍♀️ normal?

Basically like lightning crotch but keep getting it every now and then a lot more than usual 😩 keep thinking is this it? Time for baby? But no idea still not lost mucus plug or waters just getting fed up and confused as never had this with my first 2 children!
