Help!!

I was supposed to have my period the 28th of July and I didn't have it. Its now august 7th and still no period. I've got the blue veins in my boobs, I've been having stomach cramps, the other night my boyfriend and I were doing forplay and in the middle of it I started to bleed on him. So I went and cleaned myself up and I haven't blead at all since then. I've had heart burn and some nausea but I've taken two pregnancy test and they came out negative. I've never had irregular period. I used to love the smell of bleach but when I came home today I opened up the front door and I was overwhelmed with the smell and instantly I felt nauseous but the home pregnancy test says negative. What should I do?
