I really want to know what’s going on . 6 days late , since 3 or 4 days late I’ve been having light light brown discharge . All tests come back negative . I just feel different this time around like I am pregnant but idk . I’m not really stressing , my periods are irregular but haven’t been this late in a while. I started taking prenatal pills this month just because , does prenatal a affect your cycle ?
