Help, not sure.

This is my first pregnancy and I'm not completely sure about 5wks1d, I've had 3 negative and 4 positives P-test. Well I've had really bad cramping and I've bled, it's not a lot but it's not spotting. My mother had her period for the first 4 months with her first pregnancy. I'm just curious as to if anyone has any information on what this could be.
