I might be pregnant, but have started bleeding heavily, no cramps, dark red blood, but yet, it has no smell. It couldn't be my period, because my period blood has a terrible odor to it. This blood has absolutely no smell. It's just dark and red. Plus I've been clotting. Is this normal during pregnancy? Or am I not pregnant? I'm waiting to take a test tomorrow morning. I just don't know what to think. Please help.
