Early Signs of Labor???

I'm a FTM so I'm nervous as all heck but for the past couple hours I've been having sharp vaginal pains followed by pressure down there as well. Along with this my stomach gets supper tight and doesn't loosen up. I've tried drinking and changing positions and nothing is helping. It hurts to walk but not to point where I can't handle it. Can anyone drop some insight to what can be going on? I don't want to panic and it be nothing but then I don't know bc I've had braxton hicks and they never felt this tight nor this long
