Need some reassurance

I’m currently 5w3d. All day yesterday I was crampy with back pain on my lower left side. Last night when I wiped I noticed a light brown colored tint, I wouldn’t even call it spotting. Today the cramps have continued. I’ve had two previous miscarriages so I’m trying not to freak out, my doctors office is closed til the 26th. Can anyone share similar stories? Thanks for helping ease this momma-to-be’s heart.
