Pregnancy after miscarriage

I had a miscarriage November 2016 at 5 weeks and I'm currently pregnant again and I'm now 9 weeks 5 days. And I feel awful bc I'm not excited at all! I just had a ultrasound a week ago and the heartbeat was 173, baby was wiggling all around. I'm just worried and scared that I'll loose this baby to and my boyfriends mother has nothing nice to say and I just feel like I'm all alone with nobody to talk to. I keep hoping and praying that everything is going to be ok but In the back of my mind I keep thinking I'll loose my baby. I hate going to the bathroom bc I'm scared I'll find blood and face my fears, I've had few cramps when I move really quick or roll over in bed but the dr said it's normal. I just feel awful for worrying so much and feeling this way..
