I WAS having a little cramping, but not anymore. Anyone else?

I’m worried because at my first scan, the doctor said I probably ovulated late as I was measuring 6 weeks instead of 8. He said a heartbeat might be there, but it was too small for him to find yet. I was having little cramps here and there, but they disappeared maybe a week ago. Did anyone else’s cramps start to go away around 5-6 weeks? I worry about every little thing 😫
