Am I having a miscarriage?

🩷🩵

So I was 3 days late. Today is the 4th day. I took a test yesterday and got a positive. Today I've had some... spotting? Bleeding? It's dark red. Not light pink. I've been cramping too and just straight up don't feel good. I feel queezy and have a headache too. The bleeding hasn't been enough to show up on my pad yet. I put one on just in case. But there's a little bit occasionally when I wipe. Is this the start of a miscarriage???
