Hi all, just wondering that sharp pain you get in your vagina does that mean bubs head is engaging?

I went into preterm labour at 26 weeks but the hospital managed to stop it & now I'm nearly 31 weeks & this past week the b/hicks have really stepped up again & also getting this shooting pain in my vagina, just wondering if these are signs that bub may not be too far away? (never had this pain with
my first bub).

Thanks in advance, Jo
