Advice

I’ve had three positive tests. It’s faint in the pictures but it’s there. This morning I’ve had some bleeding it was a little clotted but not so much now. My last period was July 25th or so. I’ve been nauseous, sore breasts, and headaches too. I took a digital test this morning since I was bleeding a little bit and it says not pregnant.

Did I lose the baby? Retest in a few days? Or chemical pregnancy? Looking for advice
