So my last period was about 5 days late, and when it finally came, it only lasted for about 3 days and it was pretty light. Well, now this month my period is late AGAIN, and so I took a pregnancy test and it came back negative. I'm not sure if I took the test correctly, and I thought maybe I saw a faint line. Any thoughts on what I might be experiencing?? I'm only a couple days late and my boyfriend has been out of town since before my last period so I haven't had sex since then.
