6w3d spotting

I know most things say it’s normal but I had a MC in May (blighted ovum) and everything freaks me out. I started spotting, its like a very light pinkish/brownish tint mixed with my discharge but enough to freak me out. I’m on progesterone suppositories this time around to help with my levels but I was crying bc I’m scared and now having some slight cramping but nothing crazy. I went straight home from work, put in my progesterone suppository and Am laying in bed with feet up. My first US is tomorrow but trying to stay calm until then.

Should I be concerned?? Is this normal?? I had 0 spotting last time. Please help me out. Thanks.
