Cramps at 5 weeks and 1 day. Thoughts? Experience?

I am currently 5 weeks and 1 day! I had a early miscarriage at almost 7 weeks back in early September. Because of that miscarriage I have been worrying about every little thing possible. So far this pregnancy, I have felt different than the last. I have had barely any cramping up until today. Today I have had some pretty intense cramps that lead me to worry so much more. Has anyone had recurrent miscarriages so early both times before? Or does anyone else have these cramps but everything is okay? I need some reassurance and some experience to help calm my nerves or prepare myself for what could be happening. Any information is greatly appreciated!
