Implantation bleeding?

Help!?

We've been trying for so long. Idk if what I'm experiencing is a period or not. It's at the time of a period but the amount is very little ( light tampon all day... Only half full)...... It's been that way for 2 days. I've had some cramping and major boob pain. Of course I want to be pregnant but I'm also trying to be reasonable.
