I am 29yrs. old, my question is i had the depo shot in dec. after the 3 mths i didn't take it again, last month i was really sick for 2 weeks straight and it was really weird because the first two days it was kind of brown and than it was a really dark red color, about a week and a half before this i went to the hospital and they told me that there was nothing wrong, i took a pregnancy test and they have all come back neg. i have no symptoms of getting my period this month so far i should have it by sat. but because i had the depo would this make my period not normal and cause me to have a high temp and have flu symptoms for 2wks straight. i m not sure and if i am pregnant why are all of the pregnancy tests saying no? is this possible to be pregnant and have the tests say no?
