Can someone calm me down?

I have had three losses. All before 8weeks. I am now 12 weeks and 2 days and have an appointment Tuesday. I am so nervous! I felt the baby move last night but I had Spaghetti and meatballs that my hubby made and around bedtime I got the most horrible gas pains! I was doubled over on the floor in pain until I was able to go to the bathroom. I hadn't gone to the bathroom in a few days so my hubby says that that was it because once I went I was fine. But I woke up to my stomach feeling squishy And haven't felt a flip all day and since it's Sunday I can't go to the dr. I may be freaking out for no reason but after my losses the smallest things make me scared. I feel like if something had happened there really is nothing they could do. Am I being silly and I should just wait it out and calm down? There isn't any blood and my bump has hardened back up. Just got really worried last night. Any help is appreciated. Sorry if it sounds silly.
