So I went to the bathroom on my lunch break and I had some slight cramps but they were barely noticeable, and I went to wipe and had some brownish pinkish stuff come out, I recalculated wrong my next period is the 17 not the 14. Could this be implantation Spotting? And of course I can’t take a picture my camera broke when I dropped my phone, and I ovulated around 10/3/17 and my lmp was 9/19/17
