hello i was wondering if anyone can help, 

I am 6 weeks and 4 days pregnant and start bleeding yesterday very dark brown and as they day went on it went more like period blood . Today i had really bad tummy pains like period pains i had another heavy bleed this afternoon with clotting now its the evening and its very lighter with very little tummy pain. i am going to have a scan on Monday  could this be a implanted bleed or am i too far along as i have read they normal happens when your period due and my was due on on 1st January. thank you
