Abdominal Numbness ? Scared.

Hey ladies. Im 17 weeks and I'm currently feeling this uncomfortable feeling in my lower abdomin it has like a numb feeling and my stomach usually feels tight when I feel my lower abdomin but right now it dosent. I looked on the internet and all the ladies who had this problem were all over 25 weeks. So very confused and concerned but I know no one will take me to the ER. (17 and don't have license). Whenever I tell my mom I feel something is wrong she pushes is off. And I have to wait to speak with my doctor and that not for another 3 weeks. Anybody else experience this or advice please ?
