My period lasted 4 days instead of 6 this month. I’m really kinda scared because I don’t know what it could mean/ what could’ve caused it. I usually have emitter late or early starting periods but I don’t think I’ve had it end this early before. Last night I saw some blood and it was light in color but all day there had been a normal amount. I still feel a lot of discomfort in my abdomen where I would get cramps. Will it come back, wait until next month or is something wrong with me?
