I were on birth control depo shot I had got off depo on the month of July.right now it have been 3 days I have been spotting first it was brown then pinkish red so I thought oh well that s normal but it went back to brown I had took an ovulation test my friend had brought she thought it were a pregnancy test but I look online and alot of people said I could use it as a pregnancy test and most likely if it has two lines it means I m pregnant but my c band was darker then the t band on the ovulation test then I took a pregnancy test it said negative but I have been having stomach pains as in shocking and sharp pains in my stomach and my spotting is unusual.. Please help
