It the bleeding wasn't heavy it could have been implantation bleeding. My son was born 3 wks early but the docs think the dates were wrong from the start and when we worked it out I fell pg just before my last period. Also sometimes it takes a while for the hormone hcg to be strong enough to be picked up on a preg test.

I tested 5 days before my period was supose to start cause I wanted to make sure I was not pregnant before I went out drinking 5 days later my period did not start and it tured out I was pregnant

Wait a few days and test ...If your "period" was heavy then you are most likely not pregnant especially if it came on time . But anything could be and it could have been ib ...And testing 5 days is really not a good idea...I think you have something like 50% or so chance of gettting an accurate result.
