Ready to get the pain over wit!!!!!!!

I am only 34 weeks pregnant and for the past week I have been gettin these sharp pains in my lower stomach........ The pains so frustrating because I don't kno if it's labor pains or just me going through braxton hicks...... this is not my first pregnancy I had my first born at 36 weeks due to my blood pressure being high it was a normal delivery.... I've been reading about woman having their babies 5 weeks early I'm kind of scared..... I barely can walk
