Mid cycle spotting!!!

Kendra
Ok so my husband and I have been trying to conceive for almost 6 years now with no luck. I don't do any in depth charting anymore but my cycles are normal 29 days and my period only lasts 3 days. I've never ever had any kind of spotting/bleeding mid cycle but yesterday was cd 13 and I noticed that I had started bleeding very little, it was like a very light pink color and watery. It was very little and today it's still gone! Is that too early to be implantation bleeding or is it possible? In the past when I was charting my temperature and <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> I normally always ovaulated around CD10. Like I said I've never had any kind of mid cycle bleeding/spotting ever so I'm kinda freaking out lol.
