Could this be implantation or period?
Ok so I started my "period" on the 17th it's been really light then a little heavy but not really. The first day I had really bad cramps that went down my leg. Then they went away and yesterday I didn't bleed at all. And today there a little bit of blood it's really light an there barely any blood there. And yesterday I woke up and my lower stomach felt sore like I did sit ups. But I haven't done any exercise. I did have intercourse on the 6th and he came in me. I found it weird that I started early then normal. I don't ever start early at all. I would like some feed back thanks.
