Implantation Bleeding?

Hello everyone. Hubby & I have been TTC and this month we *may* have been successful! The strange thing is that right now I'm having a small flow... Yesterday it was VERY light brown, this morning it's a little more [I attributed this to being overnight] but there was more red this time. Its TOO early for my actual cycle so could it be IB? I had it with my last pregnancy but it wasn't quite this heavy [which isn't heavy, just more than the small brown glob I had last time] Any insight would be appreciated. Thank you!
