Having a Really weird period. 1st off it came 2 days late. And now its only day two and im spotting already. Plus as hard as i was cramping you would think there would be a flow a heavy one at that. I had really light bleeding that looked like the ending of a period rather than the start. Plus my boobs never stopped hurting and they normally stop once my period starts. I want to test because this is odd but i dont because i was cramping really hard and could be just having a weird period. Has anyone ever experienced something like this. Were u pregnant or not?? Im not on bc and havent been for a while. My cycles is normally on time and very predictable. And i have medium-heavy cycles. That range from 5-7 days with 2 or 3 days of spotting.
