I had my first child june 2010 my periods have been normal ever since. I got my last period july 5-9 and this month it never came, sunday august 7th i went pee at about 9 pm and i had a vary light pink discharge, not in my underwear, just when i wiped, and nothing since then. I took 2 dollar store pregnancy tests this morning, the 10 of august, both negative. Could i be pregnant?
