Is it worth going in ?

So I’m 32 weeks I don’t want to go into the ER unless its like really urgent with everything going on the symptoms I’m having are

-pelvic pressure/pain since 9pm last night. It hurts to walk/stand.

-sharp dull pain only on 1 side of my lower back

-stomach cramping on 1 side of my stomach

Friend told me it could be ‘lightning crotch’ but on scale of 1-10 this pain runs at at least a 8.
