Implantion?

Katie
I ovulated on 5/12, I am assuming that is the day, considering, the day before I had white creamy cm, then on the 12th I had watery cm and slight cramps. Today I had one small speck of blood on the to. It was tiny, and I only looked cause I am a weirdo. But the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I am currently ovulating, however, beside cramps, and sore bbs, I havent had any other symptoms of ovulating..... Could it be implantation?
