Cramping woke me up

I had a MC in September at 11+5 and recently found out I’m Pregnant again, 6weeks today, but I can’t help the anxiety and fear that I’m going to lose this one again 😭 I woke up in the middle of the night because of cramps, there’s no bleeding and I took a test and still positive…but I’m so scared I can’t get back to sleep! I’m sure the fear isn’t helping stress levels either…. Not sure who to contact as it’s a Sunday, not even sure if there’s anything that anyone can do to help ☹️
