Cramping and Spotting

Melody
Hi everyone! I'm 5w2d today and have been having continuous cramping and a feeling of heaviness in my lower abdomen, low back pain and brown spotting only when I wipe. I have spent most of the day reading as much as I can and even though everything I have read says these symptoms are normal, I can't stop worrying. I have suffered two very early losses so I guess you could say I am a bit paranoid. How do you know what type of cramping is normal and which type is something to be concerned about? I know there isn't much I can do except wait and hope for the best. Does anyone have any suggestions on how to ease the anxiety? Thanks!
