Could this be implantation bleeding?

I know you've all probably seen a million posts like this before. But I Need opinions. Hubby and I are trying for a baby. My period came this month a day or two early, and it was pretty light. Lasted about 3/4 days. Around estimated ovulation we tried to conceive. Last week and a half, I've bad heartburn, hot flashes, sore breasts. Two days ago I found a bit of clear leakage from them. All the signs of being pregnant. But yesterday I started to bleed. And my period isn't due for another 10 days. It's extremely rare for me to be that early for my period. It's never happened before.. The bleeding is light. It's a light color. It was heavy for about an hr. buts back to light and it's coming and going... I'm just confused. Lol please help!
