I should be around 7 weeks today, I have moderate cramps on and off and a sore lower back on and off, is this normal?

I’m so so worried about my first appointment. We have tried for a year and 2 months and then we finally got our first positive test, 3 weeks after his SA! I won’t have my doctor appointment till later this week or next week.. the worry if your baby is fine never really goes away does it? Praying for a heartbeat 💕
