confused

Liz

Ok... so my period was due sometime between June 30th and July 2nd.... I've been testing and all negative. July 1st test was negative. But July 2nd I got a very faint positive. I took another test on the 3rd and its negative. I'm so confused. It was faint but definitely positive on the 2nd. Help! Do you think I am pregnant? gonna tedt again today too.
