I had unprotected sex with my fiance around the 4th when I ovulated. The last time I was this late was when I was pregnant with my daughter but right away I had a prositive test. I've probably taken 6 tests all negative but had all the signs. I had implantation bleeding like my first child, my belly has gotten very bloated, and a milky white discharge. Not to mention that i'm always tired. Its been a little over 6 weeks sense my last perod. but why do the tests say negative?t
