Sharp pain in cervix?

I’m at work, and I was currently getting sharp, sudden pains in my vaginal area that lasts about a few seconds and it’ll come and go.

Not sure if it’s lightening crotch, but I’ve heard that it can also be an indication of the baby getting ready to come? Wouldn’t you also get other pains with that if that was the issue?

I’m only 25 weeks lol the baby needs to stay in there longer! Not sure if anyone else has felt this or if it’s normal but it’s a sharp pain that lasts a few seconds or a minute inside the vaginal area, feels like my cervix.
