I'm on birth control, one week last month i kept taking it kind of late (I am on Lo Loestrin so I don't think this matters), and was and am having unprotected sex. About a week or two earlier than my placebo pills, I got what I think was my period - heavy, had clots in it, and lasted roughly 3 or 4 days. I had no period during my placebo pills and brown discharge shortly thereafter. Now two weeks into my new pack pills, I got nervous and decided to take a pregnancy test. First hpt was digital and read 'pregnant'. Second hpt was standard with one line signifying not pregnant and two lines for pregnant. I took this test only an hour or less after and it read not pregnant. This morning, i took my third and final hpt and it read not pregnant.
