Sharp pains

I know this isn’t for medical advice so that’s known but im curious if anyone else has had some similar cramping .... I’m 38 weeks or so I gave up keeping track to be 100% honest but I have been good all day then bam an onset of sharp beyond sharp pain that’s lower add that it feels like it’s going in my butt 🤣🤣 tmi moment but I’ve been in a cramp filled pregnancy so I get told to hydrate and relax which I’ve done both (drinking 120+ ounces of water today and relax has been a big part of today as my toddler is still sad her daddy had to get back to his job as he only gets a few days out of the year to see her) but just curious anyone else or is this just me and if similar occurrences should I call and ask as i don’t want to bother calling as I’m always told to hydrate as is and can barely drink anymore water 🥵🥵 so I’ll just ask for opinions here and see if anyone else can relate any
