Hey guys, I was about 3 days late for my period this month and I am usually very punctual with my periods. This past month however I have been experiencing some bloating, breast tenderness (especially around the nipple, I don't have this with my period usually) tiredness and have been feeling odd sensations, that don't quite hurt in my abdomen. I got some bleeding last night (4 days after due period), it was a rusty brown red colour, but it was a medium flow. I usually feel great with my periods, could this be implantation bleeding? Any and all opinions welcome.
