I had my last period 6th of this month after I had improtected sex but I took plan be pills and today I get bleeding it's red and heavy and I feel like I'm in my period but it's so early I have irregular period but I'm worried if this is implatation bleeding it's really so heavy and color is red neither brown or pink is this mean I'm pregnant ? Help please !

We can't possibly know if you just miscarried, or what. You can't possibly know if you miscarried because the embryo would be too tiny to see.

I'm sorry can you explain more to me please

Sorry, I see you took Plan B, which is not an abortion pill.
With Plan B you can have some unexpected bleeding. It should go away by the time of your next period. However, your next period might heavier or lighter than usual. It may also come earlier or later than is normal for you.

So. This bleeding cannot be implatation bleeding ?

It is never possible to give definitive answers relating to menstruation and pregnancy. You didn't even say when you took the pills, after sex. It's not worth going into all the details because it's just not possible to say. ODDS are that it wasn't implantation bleeding. Just odds, chances, probability.
