I just can't believe it due to previous bleeding

I am freaking out!!! In a good way! 
I was hoping I was pregnant during my two week day but 5 days before my period I had some serious spotting. Starting light pink and I hoped it was implantation: then turned bright red and a little bit heavier. Then one day of no blood. Just because I was needing proof i took a test this morning 2 days before expected period. Cheap rite aid early pregnancy test. Looks positive!!! But the bleeding! IT was really red blood and more than a few drops... what can this mean? Should I wait to tell my husband I'm pregnant? Take more tests?
