First pregnancy jitters

My husband and I are expecting our first baby. I am currently 5 weeks along with an estimated due date of February 2nd. I went to the dr yesterday and we went through the whole "questions" appt and they tested my urine again to make sure everything was good. I go tomorrow to get a bunch of blood work done. Right now I'm very anxious in fear of miscarrying as we've been trying for a long while for this first baby. I don't have many symptoms. I have mild cramping on and off and feel like I have to pee a little more often, and extra CM. I've had no spotting or bleeding. I'm so reluctant to get my hopes up. I go for an ultrasound Monday even though they won't be able to monitor the heartbeat at that time. Any advice and encouragement for the first preggo jitters?! Thanks ladies!
