If it's heavy bleeding with clots and cramps and has lasted a few days, then you probably aren't pregnant and just got your period early for whatever reason.
If the bleeding is more like spotting, it could be what's called implantation bleeding, in which case it would be too early to test for pregnancy.
Either way, you could take a hpt in a couple of weeks to make sure.
Bleeding how? Like a regular flow? You COULD be and it may be too early to tell yet.
Your period is only about a week early which isn't really that weird. It could just be an off period. But if you got your period and a blood test came up negative I don't think you are pregnant.
