Thanks y'all. I'm feeling better today. It seems I get crampy when I need a bite to eat. Once I nibble a bit I settle down. The backache was something new. Thursday's my day. Thanks again for the reassuring comments.
I wouldn't worry too much. I also had terrible backaches since I found out I was pregnant. It even hurt to sneeze at the early stages. Just as long as you are not bleeding, then I think you are fine:)
Best of luck!
Try to stay calm and positive. I know it's hard to do, but until a doctor tells you otherwise, assume everything is going well. Deep breaths helped me tremendously!
