Is this a miscarriage?

It’s been 4 days and my line has not gotten any darker. At least to me I don’t think it has. And when I used the restroom this morning there was some red spotting when I wiped. No cramping or pain and I’m 4+2 today. Is this what a miscarriage is?? I’ve never had one before and was hoping maybe someone had a similar situation and they carried their baby to term. Thank you 🙏
