I am freaking out (in a good way) because I ended up getting this weird cramping feeling this morning in my lower left abdomen. About an hour later I went to use the bathroom and when I pulled down my underwear I notice a spot of blood and when I wiped it was a very light pink color. Could this be implantation bleeding? I am not due for my period for another 2 weeks and according to the app I an due to ovulate tomorrow. Does anyone know what this could mean ? Should I be concerned ?
