Okay, so my last period was from the 13th to the 15th of March. According to my period app, it was estimated to start on the10th of this month. My "period" did start on that day but it was very very light (more like spotting) and then also a lot of it was brown. It lasted a few days & then it just stopped and still no actual period has come. This has never happened to me before, so I'm pretty uncertain what to do. Answers would be greatly appreciated.
